    Short description:

    I was on my computer as normal, went away for a few hours, having shut down all programs. I came home and tried to open Photoshop, all of a sudden getting a "the program can not be opened" message. I tried a few times, before restarting my computer. Back up, the same message again. I started trying other programs, and get the same message so far, from Photoshop, CleanMyMac and AdGuard.
    Does anyone know what could be happening? My computer is possessed :eek::(

    This one is easy, and is going to be a real lifesaver later. Gatekeeper has likely revoked their entitlements because they are either A: not code signed - B: Not hardened or missing permissions - C: not meant for the operating system version. Why it happened now is that apple pushed a gatekeeper update that disabled some malware and likely some other potential "problemware".

    You can give a shot at code signing them yourself if you have Xcode, and setting permissions for them. But if they lack notary and hardening information it might not matter I think that depends on whitelists in gatekeeper and those are going to get tighter and tighter. Inconvenient yes, but will make the system bullet proof going forward and the developers get on board and do the right thing.

    Apple updated the "Malware Removal Tool", not gatekeeper, this week.

    Gatekeeper, kernel kext and the malware listings were updated and pushed to applicable systems. It's going to be a weird road for persons trying to keep certain apps alive for various reasons. It'll be a wilder ride when they lock down the system volume with the t2, That's going to brick a lot of cowboys who can't seem to leave it alone. Fun times ahead

    MRT was updated to v. 1.45 on July 10 to address the Zoom vulnerability and one other malware package.
    Gatekeeper updated to v. 171 on July 2.
    I think Apple's done with incompatible kernel data as that hasn't been updated since Dec. 19 2017.

    My fault, you're right, kernal whitelists aren't being pushed publicly.

    Google. You can disable Gatekeeper or whitelist specific apps.

    Resigning the apps yourself seems to fixed the problem with some apps!

    CS6 has a 32bit component for contacting Adobe. If it doesn't work, nor will Photoshop.

    sign the app yourself using terminal :

    codesign --force --deep --sign - /Applications/appname.app

    it should fix some apps, except for those that you reinstall after the app started crashing which I did with Adguard and Alfred 4.
    I just installed a revised Adguard app, after removing faulty one, now it working fine, if you don't want to sign the app yourself wait a few days they should be a fix
