Weak spots found in Apple’s Leopard

1 11 2007

Computer owners installing Apple’s new operating system, Mac OS X Leopard, may be making their machines less secure, according to experts.

Features of the new system designed to protect a user’s computer from hostile attack do not work as efficiently as they should, and could lead to hackers being able to install malicious software, according to the security firm Heise.

The default setting for Leopard’s firewall – which is supposed to block unauthorised access to the machine – is to “allow all incoming connections,” a report by Heise said. If a user has upgraded from an existing Mac system which had a firewall activated, the protection is de-activated, the report added.

The weaknesses mean that “system services representing potential access points for malware” are accessible via the internet, and that unauthorised connections to such services could be established “even under the most restrictive setting,” according to Jurgen Schmidt, a researcher who analysed the system.

Mr Schmidt stressed that the “peculiarities” of Leopard were “not security vulnerabilities in the sense that they can be exploited to break into a Mac,” but said Apple would be “well advised to sort them out pronto.”

In a separate development, Apple users were warned about a new ‘trojan horse’ – a type of malware – which masqueraded as a download necessary to view certain video content.

Symantec, the security firm, said that the trojan – which was found a number of pornography sites – was a sign that “the Mac is becoming popular enough that the ‘bad guys’ think it is worth spending time and effort in developing malware for the Mac OS.”

Apple was not immediately available for comment.

Lightroom update for Leopard users on the way

31 10 2007

An update to make Lightroom 1.2 fully compatible with Leopard Mac OS X 10.5 should be available mid-November, Adobe has announced.

The company says photographers can continue using the photo management software in Leopard without too much issue, but stressed that the current version of Lightroom 1.2 is not fully compatible with Apple’s new operating system.

Adobe recommends that users refer to a list of known compatibility issues published on Adobe’s Lightroom Journal Web site before deciding whether to use the current version of Lightroom with Leopard. It also issued this warning:

“The interaction between Leopard’s Time Machine and Lightroom’s catalog files is unknown at this time. Running Time Machine backup or restore operations while Lightroom is in use is not recommended until more information can be obtained,” Tom Hogarty, Adobe Lightroom Project Manager, said in a statement.

Most of the Lightroom/Leopard compatibility problems involve visual issues with the interface rather than functionality. For example, users may have to open and close left-side panels to get the Develop module to display properly. Other glitches are more serious, such as the Print module not loading at all for some Leopard users.

Adobe stated previously that its Creative Suite 3 versions of Photoshop, Illustrator, InDesign, Flash, Dreamweaver, and Fireworks are safe for continued use in Leopard.

While not directly related to the use of Adobe Lightroom, photographers commonly dealing with frequent backups and file sharing should also be aware that Leopard’s Time Machine will not support AirPort Extreme’s AirPort Disk. This is the feature that allows users to plug an external hard drive into AirPort Extreme and share its files over a secure network.

Mac OS X Hints – Convert a drive from Apple Partition Map to GUID

31 10 2007

While upgrading the laptop hard drive on my Macbook, I inadvertantly partitioned the new hard drive in the “Apple Partition Map” mode, which is reserved for PowerPCs. The normal partition type for a Intel Mac boot drive is GUID. My Intel Macbook still booted from this drive, but having my hard drive in Apple Partition Map mode had two severe drawbacks:

  1. I couldn’t install Boot Camp.
  2. I couldn’t upgrade to Leopard!

I read a couple guides online, and they involved simply copying your user folder and reformatting the drive, but I wanted a method that copied absolutely everything so that I wouldn’t have to install my horde of apps. So, here’s how I went from an Apple Partition Mapped drive to a GUID drive for Leopard, without losing any of my data, settings, or having to re-install my applications.





Mac OS X Hints – Change your login shell in leopard

31 10 2007

To change the login shell of your account in Leopard, do this… 2br Control-click on your account name in the Accounts pane of System Preferences and choose Advanced Options in the contextual menu that appears (you’ll have to unlock the pane first, by clicking the lock icon).

In the resulting Advanced Options screen, either type in the path to your preferred shell, or choose among the various shells already installed in /bin: bash, tcsh, sh, csh, zsh, or ksh. Finally, click on OK.

The note at the top of the Advanced Options screen claims you have to restart for the change to take effect, but you really just need to log out and back in again.





New Leopard Drivers Hint for new Macs

30 10 2007

Things are going pretty fast for Apple ever since Leopard came out 3 days ago. The latest of the  rumors to hit the internet is that, Apple is going to launch new Macbooks pretty soon. If you ask me the reason for this, then its pretty much simple, Apple has bundled the drivers for Intel’s GMA X3100 chipset into Leopard, that clearly suggests that Apple definitely has new Macs in the offing with Intel’s GMA X3100 on it.

Apple has included a full set of recent drivers for Intel’s GMA X3100 integrated graphics chipset, which is only built into the semiconductor firm’s motherboards for notebooks based on the Santa Rosa platform. Apple uses Santa Rosa for its most recent MacBook Pro models but equips them exclusively with dedicated graphics cards from non-Intel providers like NVIDIA, that leaves MacBooks with slower Graphics.

No other driver-related clues as to the MacBook and Mac mini upgrades have been found, but interestingly all the drivers are dated from October 11th which means that Apple finalized the current version of the drivers only days before Leopard was sent to manufacturing. Apple in the past has never included non supported drivers into OS X in the past, but this instance clearly shows that we will be seeing new Macbooks very soon..

Intel GMA X3100

Here are some screenshots that suggest the arrival of new Mac’s from Cupertino.. Steve I am dying to look at the new Macbooks!

Intel GMA X3100

If the GMA X3100 chipsets are used in the future Macbooks, its going to provide a tremendous boost to Graphics on the Mac. So I would suggest you hold on for sometime if you are planning to buy a Macbook, because Apple might upgrade them pretty soon. (One week if my guess is correct!)
