When I tried to install the printer, macOS was going to install it as a generic printer. Some further thoughts on how I got into this mess Needed Official Drivers from Brother. Setting these apps to Open in Rosetta immediately solved the issue. If in doubt, I'd recommend deleting and reinstalling the pertaining app. Right Click ยป Open did not prompt me to open it at all. this innocuous tool is well capable of recursively ruining your whole filesystem (and may even keep your system from booting). You shouldn't use chmod unless you have a good understanding of both file modes and ACLs, and more important, of what exactly the problem is, so you can fix it. I also tried to turn off anti virus and still didnt work, reinstalled the whole thing and the same thing happend. When i try to open it, nothing happens in like 20-30 sec, and then it says cant find request fille or something. finally, copying applications between computers with the correct tools might result in invalid "receipt" files (sometimes commercial apps are cryptographically locked to certain hardware ids that way - the receipt will not be valid on the destination machine). So yesterday i tried to download it again and it worked fine but the keygen just wont open.a FAT32 formatted USB stick - might ruin file names (capitalization, special characters) copying via different file systems - e.g.Making zip or tar archives with inappropriate settings will strip many file attributes.Handling program bundles with inappropriate tools often will "damage" executable bundles.
There are many possible causes for this problem, and most cannot be fixed using chmod.
