If you’ve got a fast Internet connection, a recent Mac, and US$29, what’s stopping you from downloading the just-released 10.7 Lion upgrade to Mac OS X? For many people, what stops them is being unsure whether the software they have is still going to work. In this article I’ve collected various reports I’ve run into around the web. For an in-depth analysis of Lion itself, including less obvious changes Apple made under the hood, see the by John Siracusa at Ars Technica—as excellent and detailed as his reviews typically are. And Macworld has published an article about you might run into with Lion, including the end of support for PowerPC applications which I talk about at the end of this article. (Edit: Since I wrote this article I’ve upgraded to Lion, and like many people I have been running Creative Suite 5 and Creative Suite 6 very successfully in production except for the known issues listed below.) Adobe applications As far as Adobe software such as Photoshop, the Creative Suite, and Lightroom, you can read a page that Adobe has published listing the problems they know about: Jeff Tranberry of Adobe also posted some additional comments on his blog: Anecdotally, the word is that Photoshop seems to work fine (except for droplets) as far back as CS3, the first Intel-native version. For Lightroom, the Adobe page above states that Lightroom 2.7 and later are verified to work on Lion. Full screen mode: People are asking about support for Lion full screen mode in apps such as Photoshop. On his Twitter feed (see and ), @dhowe (Director of Photoshop Engineering David Howe) explained that in Lion, full screen mode is like putting a document in its own Space. This has some important implications. In the full screen mode that Photoshop has used for years, you can press the Mac standard Command+` keyboard shortcut to switch between open documents, but in Lion full screen mode, you can’t. I tried this out in a few of Apple’s own apps such as Safari, and it’s true. We thought so. The page you’re looking for, however, is no longer available at apple.com. We do have some similar information to share with you. I did find that in apps that support Lion full screen mode, you can switch between documents if you use the Control+arrow key shortcut which is also used to switch Spaces; in other words, Lion seems to lose the traditional distinction between switching Spaces and documents. For some this might be confusing, others may see this as simpler. Also, I can’t find an Apple keyboard shortcut for Lion full screen mode, while Photoshop provides a full-screen keyboard shortcut you can customize. ( Update: Many Lion apps use Ctrl+Cmd+F to enter and exit Lion full screen, and some apps will exit full screen with the Esc key. You can customize the shortcut using the Mac OS X Keyboard system preference, but because it’s system-wide, some apps may use a conflicting shortcut.) There are reports that the, where if you have multiple monitors, you only get to use Aperture on one of your monitors, while the others get the blank Lion “gray linen” backdrop. Similarly, in Safari full screen mode, browser windows only get to live on one monitor, even if you try to drag them to another (it snaps back). Apple Preview and QuickTime Player at least let me maintain palettes on my second monitor while in full screen mode, but documents still only get to appear on one monitor. Even about Lion full screen mode. It increasingly looks like what Apple really means by “full screen” is “full single screen,” as in an iOS-style presentation. Given all that, I don’t have a problem with Adobe holding back on Lion full screen support until Apple brings the feature up a couple notches, so that at least we don’t lose the features we have with the Adobe full screen mode. Note: In OS X 10.9 Mavericks, Apple is changing how full screen apps work on multiple monitors. This may solve the current issues. Flash Player: There were some early reports that hardware acceleration for Flash is disabled in Lion. This is not true; it was based on a test with a late beta version of OS X. ![]() In the actual shipping version of Lion,. Other applications Some other compatibility notes I’ve seen: • Photography Bay has their own nice. That’s also where I learned that Nikon software support for the new Mac system will be as poor as it always has been in the past, especially if you own a Nikon film scanner. ![]() I run my Nikon CoolScan with, which is always kept current for Mac OS X, Windows, and Linux. • Canon digital SLR software:, according to Rob Galbraith. ( Update:.) • Epson pro photo printers: Read the and the before installing/updating printer drivers in Lion! • Color management: Chromix has put together an helpful.
