Mac OS X Gets First Open-source Virtualization Tool

ZD's Matthew Broersma reports:

"Sun has released a major update to its open-source desktop virtualisation tool xVM VirtualBox, adding support for Mac OS X and Solaris host operating systems, in addition to other improvements.

"Software makers such as Parallels have been making Mac OS X virtualisation software for some time, but Sun is the first to release an open-source virtualisation product for the platform....

"The free, open-source version is available for download, and Sun also sells a version under a proprietary licence with additional features such as USB support and a Remote Display Protocol (RDP) server.

"The proprietary version is also available as a free download, but only for personal use; business users must purchase licences."

Random iMac Shutdowns Continue

MacFixIt reports:

"Users continue to report an issue in which various iMac models randomly shut down during routine operation. As described by one user: ' randomly has shut down on me at least 12 times since I turned it on. I can restart it and it'll stay on for a long time. But then, randomly it'll shut itself off again.'

"This problem has been reported by several other users, but one user has a unique situation in which his computer restarts at the slightest vibration, indicating a hardware fault of sorts in the power system, potentially due to faulty wiring."

Aluminum iMacs Limit USB Bus Power

The Apple Core's Jason D. O'Grady says:

"Remember my theory about 10.5.2 causing poor audio quality in Skype? I pretty much convinced that 10.5.2 is the culprit, but there's another theory floating around out there - that it's related to USB ports.

"...It seems that only the front USB port on the MacBook offers a full powered, full speed bus. On the MacBook Pro the magic USB port is the left one, the right one is hubbed.

"The rear USB port, the one nearest the screen, is in fact already on an internal hub, shared with everything USB inside the case: the keyboard, the Bluetooth, the trackpad, the iSight camera and the infra-red receiver. Adding a four way hub to this is bound to end in disaster."

Editor's note: This impacts all Santa Rosa MacBook and MacBook Pro models and all aluminum iMacs, not just the newest ones. All Macs based on the Santa Rosa chipset only allow use of a single high-powered USB device, such as a hard drive, connected to the computer. dk

Existing USB Ports May Face Trouble Powering New Breed of Peripherals

Pertinent to current blogosphere discussion of USB port issues on MacBooks, last August ZD Net's David Berlind reported:

"Contrary to popular belief, at least from a power perspective . . . not all USB ports are created equal. Yes, they all offer 5 volts. But where they often differ, according to Verenkoff, is on amperage which could be equally important to the peripheral people are looking to power - particular power hungry devices like hard drives....

"[The first issue] is Amps vs Volts....

"Where as all USB ports support the 5 volt requirement in the USB specification, amperage varies from one system to the next. 500 milliamps (ma) appears to be the standard with many notebooks supporting more....

"Devices like USB keychain flash drives and mice run at 5v but only require limited amounts of power (or amperage). However, larger devices like 3.5" USB Drives, external speakers, etc. require significant power and often need to be plugged into the wall....

"Every computer has different amperage at their USB ports. For example, even in some of the new MacBooks, we've observed a low amperage of 500ma...."

Psystar Now Nearly Silent

ZD Net's Jason D. O'Grady says:

"Today was my second day with my spankin' new Psystar Open Computer. Following are some observations....

"This machine is almost silent, folks. In fact, I opened the case and put the sound meter about an inch from the main exhaust fan and the highest reading I could get was 52 dBA, barely. The shutter of the camera (Nikon D80) made it jump to 57 dBA, as a comparison. The fan over the CPU registered <50 dBA.

"When an optical disc is inserted the sound level (about four inches from the front of the optical drive door) ranges from 52-54 dBA. While louder than when it's not running (<50 dBA) it's not obnoxious either."

The Open Computer: We've Had Enough of It

MacUser's Aayush Arya reports:

"If the Psystar Open Computer is of any interest to you at all, you might want to know that Macworld has now tested one of these things and published the results, as promised....

"If we had our way, and the honkin' huge machine could fit inside one of those blenders, we'd have been describing a very different type of test right now and it would have been accompanied by an amusing YouTube video.

"In any case, if you've had enough of the Psystar coverage to last you a while, we assure you that we share your pain, so we're hoping there won't be any more Psystar stories from here on out - unless something really important happens...."

Have You Cleaned Your Keyboard Today?

ITWire's Stephen Withers says:

"When I saw the recent spate of newspaper and web headlines about germs on keyboards I thought they most likely originated from a study performed by or on behalf of a company that sells cleaning products. But that wasn't the case.

"The research was performed on behalf of UK consumer organisation Which?, so that blows away my suspicions of vested interests at work.

"Which? officials said tests on keyboards from a typical London office (no jokes about Londoners, please!) revealed the presence of bacteria that could cause diarrhoea and other stomach upsets....

"An accompanying Which? report on cleaning PCs suggests using a damp cloth to clean keyboards, followed by alcohol wipes to kill the bacteria...."

Today's Top-end iMac Twice as Powerful as Fastest G5 iMac

Macworld's James Galbraith reports:

"Macworld Lab benchmarks serve a couple different purposes. First and foremost, we're attempting to chart the progress of each new Apple hardware release against the previous generation. That way, we can determine if a new desktop or laptop represents a big step forward, modest progress, or no measurable difference at all.

"Take the new iMacs, which we reviewed last week at Our review of the 2.4 GHz, 2.66 GHz, and 2.8 GHz machines contained benchmarks comparing these new systems to their predecessors, released in August 2007. By running those tests, we could point out that the new iMacs improved on the performance of the previous generation without a corresponding increase in price....

"Even today's entry-level iMac - the $1,199 2.4 GHz, 20-inch Core 2 Duo - earned a 69-percent higher Speedmark score than the fastest G5 iMac ever released."

Penryn iMac Radeon HD 2600 Pro vs. GeForce 8800 GS

Bare Feats' rob-ART Morgan reports:

"One of the most interesting features of the new Penryn iMacs is the addition of the GeForce 8000 GS as a CTO option. We wanted to see how much 'fun' it brings to the 'party.'

  • Aspyr Prey
  • MacSoft Halo
  • Aspyr Enemy Territory: Quake Wars (Etqw)
  • Stone Design Imaginator
  • Legend Of Graphs

"The GeForce 8800 GS option for the new Penryn iMac is a welcome addition - especially for 3D OpenGL apps like games. At 1920x1200 High Quality on the 24" iMac, it doubles the frame rates for most games."

Psystar v. Mac mini and All 3 MacBooks

The Apple Core's Jason D. O'Grady reports:

"I've completed some initial Benchmarks of the Psystar Open Computer. The results below are from Xbench 1.3 running on the following systems....

"In short, the Psystar pretty much trounces the closest price Mac available from Apple - the Mac mini - in both overall results and the CPU test."

Editor's note: With a 10% faster CPU and a 7200 rpm 3.5" hard drive, we would expect the Open Computer to beat the 2.0 GHz Mac mini with its 5400 rpm notebook hard drive. Perhaps more surprising is how little speed advantage the Psystar has - except on the disk test, where it absolutely trounces the Mac mini. dk

How Psystar's Computer Measures Up to a Mac

Macworld's James Galbraith reports:

"What do you get when you install Mac OS X on a generic Intel-powered computer with a 2.2 GHz Core 2 Duo processor? A system that, performance-wise, falls somewhere between a Mac mini and a low-end iMac, according to our testing.

"At any rate, that was what happened when we ran Psystar's controversial Open Computer through our battery of benchmark tests. Using our Speedmark tool for benchmarking new and upgraded systems, Psystar's would-be Mac clone runs about 28-percent faster than a 2 GHz Mac mini but 8-percent slower than the new entry-level iMac."

Odysseus Eudora-Style Email Client Public Beta Released

Odysseus betaInfinity Data Systems has released the first public beta build of the Odysseus for the Mac - version 0.8.2 (there have been private betas for some time). One disclaimer that IDS strongly emphasizes that this is a very early beta, and that under normal circumstances, they would prefer not to release this early of a build.

However, they explain that given the issues that many people are having with Eudora running under OS X 10.5 Leopard, they felt it was necessary to show everyone the direction Odysseus is taking, specifically how close it's holding to the Eudora user experience, but that they emphatically DO NOT recommend using this build for anything other than testing. because it is not ready at this stage of development to be used in a mission-critical environment.

Features Currently Operational in Version 0.8.2 are:

  • Receiving Email
  • Sending Email
  • Downloading Attachments
  • Multiple Accounts
  • Built-in Address Book
  • Transferring Email Across Mailboxes
  • Replying, Forwarding, Redirecting
  • Basic Email Filtering (set default mailbox for each account if desired)
  • Basic Attachment Filtering (can define specific Attachment folder per email account)
  • HTML Rendering (via the File Menu. A future build will allow this to be enabled as On or Off by default)
  • Importing Eudora Email

Odysseus betaStill Not Operational (In many cases, the features below are already implemented to some degree, but are simply not accessible via the interface)

  • IMAP (This has actually been implemented for a couple of builds but intentionally disabled in this build
  • Signatures (This is largely done but disabled)
  • Stationery (This is largely done but disabled)
  • OS X Address Book Integration (This is largely done but disabled)
  • Sending Attachments (In progress)
  • Spelling
  • Gmail Support (In progress - this has been long-standing issue dating back to the Private Betas that they are addressing)
  • Advanced Features (Most are already in various states of completion)
  • Documentation

Now that Odysseus has moved to Public Beta, IDS will be releasing updates on a daily basis as they move closer to their revised June timeframe. Even if they are relatively minor, each build will fix bugs and/or integrate the missing functionality.

There are bugs, and a lot of work to still be done., so this version is not intended for everyday use.

Odysseus will be commercial software (as Qualcomm's Eudora was) and not open source, and will sell for $39.95, about the same price point as classic Eudora. The program is being developed with support for Mac OS X and Windows, with Linux compatibility being looked at for the future. Version upgrade prices, anticipated roughly annually, are projected to be$19.95, and if a full version number upgrade occurs in under a year's time, it will be free for users of the previous version.
