No trouble that I could trigger, but performance-wise this isn't the gain I was secretly hoping for. I think Snow Leopard just needs more RAM to run comfortably. (I have good experience on a MacBook Pro with 8 GB, and hope this one will be OK when maxed out to the 4 GB it can take.) I run my unibody alu MacBook with 4GB on up-to-date Snow Leopard. Runs like a charm. In fact, it’s only the “big” stuff (Photoshop, builds, etc.) which come close to consuming it. My wife’s recentish plastic MacBook has whatever Apple sticks in them nowadays (1GB? 2GB? can’t remember), runs decently enough for mail/web/Tweetie/etc. Would probably struggle with more intensive stuff, though.

Just noticed that (the new) option --preserveHFSCompression is the default on 10.6. As a result, if the destination volume supports compression, ditto will by default preserve the compressed format of any HFS+ compressed file instead of uncompressing it and saving it as a "regular" file. So, a documented behavior. But once again, one has to be careful with ditto's defaults from one OS version to another.

Forcing the system into an unnatural and unsupported configuration will do nothing to help you solve any such issue. The method you've already discovered of starting Apache with the arch command is the correct means of dealing with a recalcitrant Apache module; gdb also has builtin commands to control the architecture of a binary being debugged. All messing with the system's bit width will do is muddy the issue by hiding it behind whatever other mass of problems that messing causes, rather like trying to use a pair of maladjusted pliers to remove a splinter from your back in total darkness. >> I know of issues that can prevent booting if you force 32-bit binaries to be used on certain configs due to assumptions they make about their environment. > ...if as you seem to imply, there is a way to force it across the board, I'd still like to try. (This Mac swaps & beachballs a LOT less if I set just *Safari* to run 32-bit, or return to 10.5.8 on another partition.) This suggests any number of potential issues, but what you're asking for simply doesn't work. The only sure-fire way to force the entire system 32-bit - don't do it! - is to PERMANENTLY disable all 64-bit code by piping find through lipo under sudo, at which point there's no going back short of reinstalling the OS and anything else that may have been installed at the time. Since as Shantonu wrote, forcing 32-bit will probably make it impossible to boot your system, you'll have destroyed your OS installation. If you're seeing heavy swapping under 64-bit, it's possible that your system has too little RAM to run in your configuration, that your hard drive's free space is critically fragmented, that your hard drive just doesn't have enough free space, that there's some corrupted cache or preference file messing with your applications, that you have a bad memory module in your computer, that your computer is too old to run 10.6 successfully, that Safari in particular has some 64-bit issue, that you're running some other ill-behaved application - this list continues on ad infinitum. What you need is a sampler output during the beachballing to see what's really going on, and to look at Activity Monitor to see where your RAM is going. -- Gwynne _______________________________________________ Do not post admin requests to the list.
