Last time I profiled it, it was still a decent performance win (Sierra, I think). NSZone is really optimized around tiny mallocs, for NSObject sizes rather than bitmap image sizes. Running FVAllocatorPerf on a 3.5 GHz Mac Pro with 10.13, I get: FVAllocator: 3.52 seconds for 20000 iterations CFAllocator: 6.21 seconds for 20000 iterations > I am glad I made a copy of Xcode 9 before updating to 10.

BibDesk still had PPC support? I thought Xcode had dropped that years ago! FWIW, the MacTeX working group recently decided that MacTeX would officially support only versions of OS X for which Apple still provides security patches. Compiling, packaging, and testing had basically become impossible. http://www.tug.org/mactex/SupportedSystems.html My Pismo PowerBook G3 still worked last year, and I assume it would still power up if I want to run Leopard very slowly. Hard to believe it’s nearly 20 years old. The major downside of dropping support for older versions is all the bullshit deprecation warnings, for which I blame iOS and Swift. They’ve really gotten out of hand, IMNSHO. — adam _______________________________________________ Bibdesk-develop mailing list Bibdesk-develop@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bibdesk-develop
