Doing this efficiently requires a lot of RAM for a buffer cache. Wikipedia has a good article on this type of FS. It’s a new (and high-performance) implementation of the log-structured filesystem concept. ZFS does not need journalling because the filesystem is basically just a journal itself. The referenced book does not include anything about ZFS-style systems because they did not really exist when BFS was being written. HFS+ added features, like journalling (which theoretically should alleviate some of the bottlenecks, depending on how it’s implemented), but the complicated catalog structure is still there. Both the original and the plus versions have a complicated metadata structure that cannot be safely accessed and updated in parallel, and which does not make the most efficient use of the disk and the cache (after all, the early PCs would not waste much memory on something unnecessary like a disk cache). HFS was perfect for the early macintosh, which was at the beginning of the desktop computer, but it has serious problems on a modern multi-program and multi-user system. The only thing that comes close in structure is ReiserFS (not sure how the B-tree differs between 3 and 4, but I’m basing my words on what I’ve read about 4). In particular, HFS and HFS+ have a very radically different filesystem structure from every other filesystem. I think you could do with some extra reading (I don’t really want to be insulting: here’s a great source from the guy who did BFS for BeOS about the internal structures and merits of several commercial FSes. Other software reporting crashes and other errors include: Backup Bouncer, Books, Boxee, Butler, Camino, CheckPoint SecureClient, ClamXav, Cocktail, ConceptDraw Pro, DataBackup, Dave, Disc Inventory X, DiskWarrior 4.1, Electricsheep, Fallout II, Flip4Mac 2.3.0.7, Forklift, Fruit Menu, Google Gears, iStat Menus, iStumbler, Leopard Cache Cleaner, Leopard Cache Cleaner, Macromedia FreeHand MX 11.0.2, MailFX Pro, MenuMeters, Mirage, NodeToad, OneSwarm, PGP Desktop, Plex, Protector Suite, QuicKeys 4.0.3, RealVNC, Reader Notifier, Apple Server Admin 10.5.3, SmartScroll, Sonos 3.0, Sticky Windows, TinkerTool, TivoDesktop, Undercover, Vectorworks, WindowShadeX, WireTap Studio, and X-Lite.First you state the HFS+ is adequate and then you ask if ZFS is journaling. While Microsoft Office 2008 runs fine, and Microsoft Office 2004 works under Rosetta, there is no report yet on the older Microsoft Office:X. Readers are encouraged to contribute their own compatibility findings.Īdobe gets an immediate hit on its entry-level Photoshop Elements application, which apparently after restoring from Time Machine the app “gives a licence error”. So what other Mac apps get a frosty reception from the Snow Leopard?Ī wiki-based website called “ Snow Leopard Compatibility: Which apps work with Mac OS X 10.6?” includes a Mac OS X 10.6 Snow Leopard Compatibility List. Thankfully, if you later try to launch a PowerPC app, Snow Leopard will pop up a window to explain that you need Rosetta and offer to install it for you (via Apple’s Software Update utility). (That oh-so easy Snow Leopard upgrade chart ain’t looking so simple now, is it?) Snow Leopard has Rosetta turned off by default, so CS1 and CS2 users require a Custom install of Snow Leopard. It turns out, after some initial testing, that CS3 does work on Snow Leopard – and Adobe’s wording about “not supporting” CS3 merely demonstrated its desire to abandon CS3 support rather than actively force its users to upgrade their expensive software.Īdobe Creative Suite and Creative Suite 2 (CS1 and CS2) are not Universal software applications, just PowerPC – so they require the Rosetta emulation. It therefore requires Rosetta emulation to run older PowerPC-based software, rather than Intel/PowerPC-friendly Universal programs.īut as the new OS is installed on more and more Macs tales of incompatibilities are starting to emerge.Īdobe got everyone in a panic earlier in the week when it stated that it was supporting only the current version 4 of its Creative Suite design applications. The latest version of Apple’s Mac OS X operating system, Snow Leopard, will install only on Macs (and Hacked PCs) running on Intel processors.
