Mac OS X 10.7 Lion System Requirements
Mac Pro: Apple says nothing about Snow Leopard in the release notes. Security Focus says that QuickTime 7. Snow Leopard, however, comes with QuickTime 7. Is that version vulnerable or not?
We may suspect it's not, but we don't have any official word. Note that in Security Update , released after the QuickTime update, the release notes specifically say that the update is for Tiger and Leopard and is not required for Snow Leopard. Too bad no one thought to make such a clear statement about QuickTime 7. What to do? The normal behavior of Software Update and Apple installers is to avoid offering to install updates that aren't required for a specific Mac and OS version.
Mac OS X v Snow Leopard - Technical Specifications
Lacking any other evidence grumble grumble , we'd infer that the QuickTime 7. I have a license for QuickTime 7 Pro. Will that still work in Snow Leopard? In fact, if you have a valid Pro license on a Mac you update to Snow Leopard, QuickTime 7 should be installed automatically with the Pro features enabled. What happened to QuickTime VR?

Instead, it offers to open QuickTime Player 7 instead if available. However, Apple is encouraging web content producers to use its new HTTP streaming protocol that works with any web server and does not require specialized server software. We'd say the writing is on the wall for QTSS. Can I still run it in Snow Leopard? However, unlike Leopard, Snow Leopard does not install Rosetta by default. If you did not choose to install Rosetta when you originally installed Snow Leopard, you have two choices: If you have a live Internet connection, you can double-click any PowerPC program to launch. When you do, a dialog box will appear, saying that you need Rosetta to run this program and offering to download and install it for you.
Is there any drawback to installing Rosetta? Not as far as we know at this point. The Rosetta software does not require much disk space and only runs when needed. I want to install Office , which is a Universal Binary. Office is a Universal Binary and does not require Rosetta. But the Office installer is a PowerPC application, so Rosetta is required for the installation, but not for running Office once installed.
You may experience this hiccup when installing other compatible programs as well. For a long time, Macs have had Wake on Demand also known as Wake on LAN for wired Ethernet connections, which makes it possible to send a magic packet to a sleeping computer on your local network in order to wake that computer up so that you can access it remotely. Until now, though, it wasn't possible to use Wake on Demand to wake sleeping Macs that connect to the network wirelessly.
Being easily pleased, we were happy to learn that Snow Leopard would include support for wireless Wake on Demand. As it turns out, the feature is available in Snow Leopard but for a smaller group of users that we hoped. According to Apple, your system must meet the following criteria: Supported Macs will say "Wake On Wireless: If your Macs and network meet the requirements, then to activate the function, you just need to turn on "Wake for network access" in the Energy Saver preference pane.
The AirPort firmware 7. About Wake on Demand. So far, we haven't seen any explanation of why Apple decided to reduce the options for font smoothing. However, if you're in an experimental mood and you're comfortable using Terminal, Mac OS X Hints has the following tip: Re-enable LCD font smoothing for some monitors. Is Blu-ray supported now? Blu-ray video is not supported by Mac OS X Since the Blu-Ray license requires extensive changes to the system software for video playback, we don't expect it anytime soon.
Blu-ray data is possible using third-party support for Blu-ray drives for example, Roxio Toast Titanium. Your PowerPC Mac is still just as capable as it was the day before Snow Leopard was released, and while the time will come -- perhaps soon -- when most new and updated programs will require an Intel Mac, that hasn't happened yet.
So you can take your PowerPC Mac and Keep using it just as you've been doing until you are truly forced to upgrade, either by some external requirement or by your growing techno-desire which we recognize as a valid reason. Convert it to a new use: Pass it on to a friend or relative who's further behind the curve. Donate it to a local non-profit, charity, school, church, or other worth organization. If you really want to be a hero, donate your time to set it up and keep it running as well. Sell it through eBay, Craigslist, or some local venue. Would there be any speed increase?
If you remove the PowerPC code using a "slimming" application , you will save a little space, but it's unlikely you'll save very much. The PowerPC-specific and Intel-specific code makes up only a small part of the bulk of most Universal Binaries; the ajority of the size is taken up by the resources shared between PowerPC and Intel versions.
You're likely to save much more space by removing unneeded languages. How to I turn it on? The scrolling list on the left includes a number of default text substitutions to turn c into a copyright symbol, for example , some of which are turned on by default. Note that this list is global -- there is no way to create application-specific substitution sets -- and it is currently only used by a few applications, such as TextEdit and Mail.
In those applications, substitution can be turned on and off for all documents or for individual documents. Apple claims that Snow Leopard takes much less disk space than Leopard. How does it do that? Remember that Snow Leopard's space savings relate only to the disk space occupied by the system itself.
OS X Lion system requirements
If you have GB of music and video on your hard disk, it's not suddenly going to shrink to GB. That said, Snow Leopard saves disk space in two ways: In Snow Leopard, Apple has compressed most of its own applications and system frameworks on disk.
When launched, they are re-expanded into memory for use. Apple has also chosen to skip installing some items that are not immediately needed. In particular, Snow Leopard by default installs printer drivers only for printers local to or known to the Mac it's being installed on, rather than installing drivers for all supported printers. While the two changes above create real disk space savings, a separate change may create some confusion by providing apparent savings. Until now, Mac OS X has computed disk space using powers of 2: Snow Leopard, in contrast, uses powers of Does my Mac support OpenCL?
What good does OpenCL do? However, programs must be specifically written to take advantage of OpenCL. Until they are, OpenCL support will make no difference in your Mac's performance.
