Hmmm, I would have sworn it would be renaming. Glad I didn’t put money on it.
Is the app in the applications folder? I don’t know if it matters but everything’s worth a try I guess.
Your next port of call is the Console to see if there’s any error reporting. I just found my playback thread and this is how I tracked my problem and Kattkieru confirmed there could be a naming “issue”. (The stuff in my error report about Scanner Private Context and Vendor ID is a Canon scanner bug so ignore all that if you read that thread).
It seems that the blender app may not always be called “blender” but may need a unique name (as downloaded) - though out of eight Blender folders on my system, only one contains an executable not labelled “blender”. Maybe some CVS have unique names? (Note: I usually rename the parent folder and as far as I can tell, this hasn’t broken anything but nesting folders might be a problem?)
Maybe download a new blender and drag it, unchanged, into your Applications folder (drag other Blenders out first if need be to prevent overwrite prompts). And see if this works.
