I can replace the hard drive for any brand or has to be the same thank
I have a imac 2011 but the hard drive is mess up can I buy any brand and it would work fine?
The brand should not matter as long as the form factor is the same. The 27 inch iMac 2011 uses a 3.5 inch drive. So you’ll want a 3.5 inch replacement drive. If you want to use an ssd, you’ll have to order an adapter/bracket to allow a 2.5 inch drive to fit as ssds only come in 2.5 inch form factor.
I hope this helps. Feel free to ask more questions
