Hi guys! Recently bought a Mid 2012 2.5GHz MacBook Pro. As soon as I got it, I installed High Sierra, then migrated from my old 2008 MacBook Unibody (which had unsupported Sierra installed) with the migration came all my apps - Adobe CC, Microsoft Office, iMovie, etc. Every time I boot up my Mac, I get the following pop up message: SIP Enabled SIP is enabled on this system. Running with SIP enabled could cause issues, such as USB not working. To rectify this, please boot into your system's Recovery Partition or your Sierra Installer USB drive, open Terminal, and run the command "csrutil disable". Has this got something to do with my old Mac running unsupported software? How do I go about fixing it - is there a file or something somewhere that migrated with my Mac that wants SIP off? As I obviously now have a system that can run High Sierra by default, seeing this disable SIP message is simply annoying! Any help would be massively appreciated!! --- Post Merged, Oct 18, 2017 --- @dosdude1 maybe you'll know?!
