So yeah i was searching around for a cracked fl studio 20 version (for mac), and found one. all files included.
1. open and install the "flinstallationfile".dmg
2. after completion, disable in and outgoing connections for FlStudio (firewall)
3. when done generate the FlKeyReg.Reg file with the keygen
4. go launch fl studio 20 and go to help > about > unlock with reg file
5. locate and choose the newly generated reg file and apply it
6. restart fl studio, and maybe restart your mac for good measure.
cred to @wasdasd (idk how to tag people) but he managed to code a patcher for windows so check that out
idk how to do a virus scan so someone gotta do that ;?
