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. You might not notice this will obviously slow down your Mac if too many applications open with your Mac. 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).a FAT32 formatted USB stick - might ruin file names (capitalization, special characters) You can install the free edition of CleanMyMac X and open the Maintenance Tab to find. copying via different file systems - e.g. They are rather a family of apps and not a particular software.So, do proceed at your own risk and only if you’re 100 percent sure the app you’re trying to launch is stable and secure. Making zip or tar archives with inappropriate settings will strip many file attributes The xattr -cr /path/application.app command lets you remove all your file or app attributes (metadata) leaving your Mac unable to assess if that file or app is stable or secure.Handling program bundles with inappropriate tools often will 'damage' executable bundles.
