So I have the Macbook Air 11 inch( 6'1) and I decided to install OCLP as a friend told me about it, I decided to upgrade to seqouia as I have 500GB on the hard disk and thought it was enough. Installed it and things were great up until the update OCLP 2.4.0, when it came out I updated it and everything was fine and then one day the sound just stopped working, I hadnt noticed since I had my headphones plugged in at the time but when I took them out no sound ? I plugged the headphones in and out a few times but the sound output swaps to the internal speakers for like 10 secs and then goes back to the headphones even when they're not plugged in. Basically they only work when my headphones are plugged in but as soon as I plug them out no sound. It remains the same as if I never plugged them out in the first place. I have tried everything from restarting to and EFI boot and I'm now considering removing OCLP but I use this Mac for uni and my whole life is on here, CAN ANYONE HELP ME ?? i would reallly appreciate it
TIA
