News & Opinion
Hardmac's Lionel weighs in on the iMac hard drive issue (see last week's Mac News Review for more details), noting that it has several consequences, but most importantly that it's now impossible to replace the hard drive of the 2011 iMac without going through an Apple Retailer to get an identical disk, which (of course) will be sold at a price three times higher than anywhere else.
However, in Apple's defense, Lionel observes that the main goal of this change is to monitor disk temperature as precisely as possible, which is absolutely necessary in a confined architecture such as the iMac's slim case, and the only way to keep the fans running at the right speed to cool down the disk while keeping the computer as quiet as possible, without the fan blowing at full speed all the time.
Lionel believes that Apple went with its "Out of Bandwidth" temperature monitoring system to avoid using SMART, which prevents data access momentarily when it is used. The iMac checks drive temperature "very often", so this avoids a potential performance issue.
In his original report about the roadblock to replacing hard drives in the new 2011 iMacs due to a proprietary temperature sensor (above), Hardmac's Lionel expressed confidence that there must be a way to deactivate or to trick the problematic sensor. He follows up saying that it didn't take long to find a solution, which is that provided by Apple on models available with an SSD: short-circuit pins 2 and 7 on the power supply cable.
Lionel goes on to note that the first iteration of the temperature sensor issue was introduced in the 2009 iMac, with Apple initially using connectors added to most hard drives for the purpose of programming and testing the disk. The drawback was that each hard drive manufacturer had its own connector, so the 2011 model uses a new system with all information now going through pin 11 of the power supply connector, normally used to light-up a LED during disk activity. In order to change the use of that pin, specific firmware was needed, which explains the reason that only disks sold by Apple in the iMac don't have problems.
Lionel observes that this was quite a radical choice, far from established standards, but in the end it should not cause any big problem in replacing hard drives in these computers.
Publisher's note: Without temperature monitoring, hard drive heat could become an issue in the iMac's confined spaces, so replacing the hard drive is done at your own risk. If you do elect to do so, look for a drive that runs cool. dk
OWC blogger Larry expands on some questions, context, and additional technical details concerning the now infamous 2011 iMac hard drive replacement issue, affirming up front that he thinks these are absolutely the best iMacs ever and noting that the following model drives were found in systems OWC has received:
- Seagate ST3500418AS 500 GB 7200 RPM Barracuda 7200.12 7200 RPM 16 MB SATA 3 Gbp/s
- Seagate ST31000428AS 1 TB 7200 RPM Barracuda 7200.12 7200 RPM 32 MB SATA 3 Gbp/s
- Western Digital WD1001FALS 1 TB Caviar Black 7200 RPM 32 MB Cache SATA 3 Gbp/s
Larry notes that you don't get to pick what brand hard drive, cache, model, etc. are installed at the factory, but Apple iMac Specs confirm all factory hard drives are 7200 RPM and cautions that the base $1,199 iMac model doesn't have any drive configuration options and is only offered with the 500 GB capacity drive.
OWC has tested the new iMacs with a variety of drives and reports that regardless of which drive was factory installed, any of the different drives received in any of the iMacs worked fine in any other. Larry further notes that each hard drive manufacturer currently has different pins for the available thermal sensor line found on today's hard drives, which means owners of 2010 iMacs can more easily replace their factory hard drive with a retail drive, as long as they stick with the same make (although he cautions that it's still a major job just to open up these machines, independent of other challenges), but if they want to use a different make drive, you'll need to make some modifications.
However, while OWC has done other testing with external options, it is so far inconclusive, so they can't say anything is 100% definite yet other than either Apple has custom firmware in its drives that enables something, or Apple has firmware on the drives that it looks for to use what is there anyway, with the bottom line being that workaround options are in play, and with further testing, OWC should be able to be confident in one solution or another, noting that only a very small percentage of iMac users are ever going to want or need to replace drives in their computers, observing that Apple has made that hard enough as it is, but for the few, it didn't need to be this hard.
Hardmac's Lionel notes that difficulties associated with replacing the hard drive in 2011 iMacs led to an initial workaround of short-circuiting some pins in the power supply of the hard drive, but that was a bit kludgy, and that some of his readers from Gravis, a German reseller, developed a more interesting and elegant solution - a little component to replace the sensor inside the hard drive that can measure the temperature and send it to the motherboard to regulate fan speed. It's called cBreeze (English translation by Google Translate) and will work with any 2009 or later model of iMac, and is projected to be widely available in June.
Christian Apple aficionados are inclined to joke about "the church of the Macintosh"* but the BBC's Alex Riley reports that a team of neuroscientists scanned the brain of an Apple fan and it showed that the brand was stimulating the same parts of the brain as religious imagery does in people of faith.
Secrets of the Superbrands explores why companies like Apple and Google have grown explosively over the past few years and elicit passionate loyalty from their customers, and is to be broadcast on BBC Three at 2100 BST on Tuesday, 17 May. Or watch online via iPlayer (UK only).

PR: mozilla.dev.planning blogger Christian Legnitto provides this summary of Mozilla's Firefox update roadmap:
- Current working Firefox 3.5 EOL plan can be found @ https://wiki.mozilla.org/Releases/3.5_EOL
- We have no intention to release another 3.5 update (but if we need a chemspill before the plan is implemented we will discuss it)
- We have a plan with investigation work and a backup plan if the investigation says our desired plan is unworkable
- For both plans the end result is sending 3.6 as a minor update for 3.5 users . . . the difference is merely the implementation method and timetable
- No real actions need to take place until June, so there aren't pressing requirements that could impact the new release process
- Firefox 3.6 has different considerations and a draft plan will be sent around in due time
There has been a of discussion about 3.5 EOL and we have a plan (already being implemented) documented @ https://wiki.mozilla.org/Releases/3.5_EOL . The plan was created with input from the security team, QA, product, and RelEng.
The main takeaways are:
- We want to do this quickly
- We want users to self-select into running Firefox 4 if at all possible (dangle the carrot)
- We don't think self-selection will ultimately get us to the place we need to be
- We will force 3.6 on 3.5 stragglers not choosing to update to Firefox 4 or 3.6 (give them the stick)
- We feel comfortable making the major update choice for users because a) the versions are very similar and b) we'd rather lose a small amount of miffed users than leave a large amount of users vulnerable
...we intend to ship Firefox 3.6.18 (the update shipping at the same time as Firefox 5) to 3.5 users when it is released. This is highly dependent on the outcome of https://bugzilla.mozilla.org/show_bug.cgi?id=650030
If the bug is not resolved in a timely manner we will instead do an advertised prompt to Firefox 5, let it sink in, and then update users to 3.6.18 via automatic update.
Publisher's note: System requirements for Firefox 3.6 appear to be identical to those for Firefox 3.5, so 3.5 going end-of-life shouldn't be an issue for anyone. Firefox 4 no longer supports OS X 10.4 or PowerPC Macs, making upgrading problematic to users of either, although there is an option: TenFourFox is a custom port of Firefox 4 to PowerPC hardware and works with OS X 10.4 and 10.5. Mozilla recently released the first beta of Firefox 5, which is scheduled for public release on June 21. dk

PR: MintPPC is a Linux distribution for 32 and 64 bit PowerPC computers based on Linux Mint LXDE, ported to Debian/PPC. The idea behind MintPPC is to provide a fast, good looking, lightweight desktop manager that runs well on older G3 and G4 machines, and also supports 64-bit G5 powered Macs.
MintPPC is also directed to desktop users who want a very fast system without the need to install software themselves, and designed to be both an easy to use and complete solution.
The developers say that one advantage of this distribution for PowerPC users is that a few bugs, which are always present in Debian/Ubuntu, have been overcome. For example, after installing MintPPC things like battery status meter, laptop sleep mode and sound will work out of the box.
MintPPC is not affiliated with Linux Mint but it uses the same underlying source code. MintPPC was first released as Linux Mint LXDE Debian Lenny in May 2010. In October 2010 MintPPC 9 was released which was based on Linux Mint LXDE 9 (Isadora) and Debian Squeeze. Because of a conflict with the Linux Mint team, the name of the distribution was changed into MintPPC. MintPPC is developed by Jeroen Diederen (Linuxopjemac), a Dutch Linux enthusiast who also owns a general website about running Linux on Macs and by Tony Cygne (Ant2ne), an American Linux enthusiast.
Demonstrating how compatible MintPPC is, check out this list of Macs onto which MintPPC has been successfully installed:
- PowerBook G3/400 (Pismo)
- iBook G4/1.42 14 inch
- Beige G3 (OldWorld)
- PowerBook G4/500 Titanium
- G4 graphite
- iBook G3/900
- iMac G3/500 Summer 2001
- iMac G4 iLamp
- PowerBook G4 Aluminium
- iBook G3/300 clamshell
- eMac G4/1.25
- PowerBook G4/1.5 Aluminium
- eMac G4/800
- PowerMac G4 3,5 Quicksilver
- PowerMac G5
- eMac G4/700
- PowerMac G4 3,4 (Digital Audio)
- G4 Cube
- Dual G4 450
Based on Lubuntu 10.04, Linux 2.6.32, Openbox 3.4.10, LXSession 0.4.3, and Xorg 1.7.5, Linux Mint 9 LXDE features a complete desktop computing experience while being easy on system resource usage thus making it suitable for older hardware and situations where speed is a crucial factor.
Featured improvements in this release:
- LXDM, improved PCManFM2 file manager, VLC installed by default, 30,000 applications catalogued and reviewable both online and in the new software manager, brand new incremental backup tool for both data and software selection, 3 years support.
- Linux Mint 9 LXDE is the first Mint release to use LXDM as a display manager. It's smaller and faster than many comparable display managers and offers excellent localization support. It can also be themed and is easily configured for automatic login.
- The LXDE file manager has been completely rewritten to offer better support for mounting and unmounting filesystems, native Trash support, and autorun when certain types of media are inserted.
- The Software Manager was rewritten from scratch. It features the best ideas from the original Software Manager, Gnome App-Install and the new Ubuntu Software Center. It's also much more efficient than the previous version, handling 30,000+ packages and asynchronous installation/removal of applications in less than 1,000 lines of code.
- Number of packages: The Software Manager now features all the packages available on your system. That's about 30,000 packages to choose from, compared to around 300 in the previous version.
- Apt daemon: When you install software, you don't have to wait for the installation to finish. You can browse through the Software Manager for other applications, or you can simply close the manager. The installation continues in the background. If you decide to open the Software Manager again, it will track any ongoing installation happening in the background and inform you about its progress. At any time you can cancel an installation and monitor the progress of ongoing operations.
- Visual improvements: The new graphical interface is inspired from the Ubuntu Software Center and it uses the Webkit engine to render some of the screens in HTML/CSS. It uses a single-click navigation system and lets you browse categories, applications, screenshots and even websites from the comfort of a single window.
- New Backup Tool - The Backup Tool was also rewritten from scratch. Linux Mint needed a solid backup tool that would allow you to easily perform fresh installations without losing what's important to you: Not only your data, but the selection of software you installed. With this new tool you can upgrade to new versions of Linux Mint by performing fresh installations from the CD, you end up with a clean system containing your data, your preferences and even the software you previously installed.
- Software selection: The Backup Tool can identify the software you installed in Linux Mint and save this selection as a list. It can also restore that selection of software on a different computer or after the installation of a new version of Linux Mint.
- The Backup Tool identifies the software you added to Linux Mint
- Incremental backups and compression: The new Backup Tool can check differences between files in a variety of ways and perform incremental backups and restorations. It can also archive and compress on the fly.
- Integrity check: Thanks to an integrity check, the Backup Tool verifies each file after it's been backed up (this check can be disabled to make the backup faster).
Documentation: A full tutorial on how to use this Backup Tool guides you through the process of upgrading Linux Mint to a newer release.
Better look and feel
- Backgrounds: The production of artwork for Linux Mint 9 was outsourced to provide this release with a choice of quality backgrounds. The default background is unbranded to give the desktop a more elegant look and you'll find quality alternative backgrounds installed by default. Additional backgrounds made especially for Linux Mint 9 were packaged in "mint-wallpapers-extra" and previous backgrounds were packaged in "mint-wallpapers-previous-releases". These packages are available in the repositories.
- Welcome screen: The welcome screen is now rendered in HTML. It links to the same important resources as before (how to know more about Linux Mint, where to get help and how to contribute) and it adds links to the most important parts of the new Linux Mint Community Website, its collection of tutorials, its idea pool, its software portal and its hardware database. The new welcome screen is rendered in HTML to give the desktop a more welcoming look.
- Update Manager: The Update Manager uses a new icon set that integrates better with the desktop. It also distinguishes between more error scenarios than before and doesn't consider it an error when it cannot assess the state of available updates anymore. In previous versions of Linux Mint, users would see a broken lock when Synaptic was open, or when the connection to the Internet was down. In Linux Mint 9 the Update Manager only show errors when something is actually wrong and requires action.
- Default software selection: VLC is now installed by default for media and DVD playback.
- Local repository and Gnome-ppp: Linux Mint now includes a local repository activated by default. This repository is located in /usr/share/local-repository and it contains firmware for Broadcom wireless adapters and Gnome-PPP. You can also add packages to it and update the repository by running the ./update-repository script in /usr/share/local-repository.
- Apt hold/held/unhold commands: New functions were added to the Linux Mint "apt" command. "apt hold", "apt unhold" and "apt held" are shortcuts to "dpkg - get-selection" and "dpkg - set-selections" which let you easily hold updates for selected packages.
