I've accidentally found a strange workaround - if i shut down my laptop, plug thunderbolt into a projector or external monitor for display mirroring, then do an SMC reset / restart, everything works normally. No idea what kind of problem this points toward, but at least I can make music in the meantime. Going to post on a more general mac forum and see if anyone has any ideas. Might also try deleting all library cache, saved application states, launch agents, startup items etc to see if that helps. Thanks

Ah, thanks everyone, will have a little look into firmware updates. Sounds like it's a bit of a tricky one - will read up on the SATA cable issue as well and update here if I find anything useful . cheers

Hi everyone, first time poster longtime lurker and this forum has helped me understand PD a lot better so firstly thanks a lot for that

I recently changed my HD for an SSD and upgraded RAM on my old macbook pro, running mavericks 10.9.5. For the first few days PD and other audio programs worked fine, however now when I bang an [openpanel], it loads the window to select a sound file, then immediately hangs with beachball and needs to be force quit.

This happens on both 0.47, 0.48, so I installed 0.49 and the same thing happens. Interestingly other standalone audio programs like Spear audio analysis and Forester also crash when I try loading in a sound. From doing a bit of research I found out that PD uses tcl/tk wish to open so might be a corrupted library file or kext or whatever but don't really know how to troubleshoot.

Tried a fresh install of purrdata too, which actually doesn't even open - just hangs on startup. This second issue is also happening with Logic 9 freezing on startup, which was the reason I decided to install the SSD, and it seemed to be fixed for the first 2 weeks but is also happening again (although a workaround is opening from a specific logic file rather than clicking icon). Running macbook in safe mode makes everything work normally.

Wondering if at this point I should try a fresh install of a newer OS (and losing Logic 9), but wanted to ask if anyone has encountered anything similar first? Even getting a better idea exactly how to troubleshoot these sorts of problems on mac would be great.
