Q: macOS Sierra panics on iMac 21.5-inch Mid 2011

Try to Reset the System Management Controller (SMC) on your Mac - Apple Support

The reference to vm in the panic call may be indicative of a RAM problem.

Did Corsair certify that your RAM was compatible with your Mac?

I googled the part number and note several reports of incompatibilities (along with some successes).

Ella's suggestion may help, so try that first.

You can try testing the RAM with Rember: http://www.kelleycomputing.net/rember/

However, the best test is to replace it with the original and see what happens.

If it is only one stick that has gone bad, you can try pulling two sticks and test. Swap them out if no change.

You can swap out individual sticks to determine if one is causing the panics.

Hi, Interestingly I'm having the same if not similar problem and I also have 16gig of ram in my mac but my memory was supplied and fitted by Apple in the new product. I don't know the answer to this but just wanted to say I'm having this problem. Here's one of my panic many strings below, I also did a clean system install to try and fix the problem but it didn't:

Hi, Interestingly I'm having the same if not similar problem

No, you're not. Remove Ambrosia's Audio software using their uninstaller and test. If you need more assistance, please start a new post as this is just cluttering up NielsR's question.

As I noted before, you can test for a bad stick (not likely all went bad) by pulling two of them.

If no panics, swap the two with the other two and test.

If you have a panic with two, swap one of the installed ones with one of the other ones (keep track of which is which).

If you don't have a panic, it is the one you removed.

Keep swapping until you isolate to one.

However, Rember will likely determine the one that is bad, if it is.

If you look at the support page for Rember, it states this:

If have experience replacing hardware, the only way to locate defective memory chips is by deduction - guess and check or split-half method troubleshooting. This may be updated in the future. You may also attempt to run the Apple Hardware Test CD or DVD that comes with most Macs. This may give more information (if it finds the problem).
