MacBook Pro Stuck on 25% at start up screen after changing RAM sticks

it can't be anything else because this only started happening after I changed my ram sticks. I bought these ram sticks for my PC a while ago, but when they arrived the packaging clearly said they were for MAC, and the sticks themselves say mac memory on them, w the Mac logo too. I was worried they wouldn't be compatible with my Laptop PC but I looked it up and found out that a lot of laptop pc's are compatible w mac memory sticks. So they're definitely MAC ram sticks and I definitely think me uograding them is what is causing this to happen . How can I fix this? Thanks in advance for the help

MacBook Pro, 13"

Put the original Ram back in, return the ones you bought. Get correct replacements from OWC or Crucial only.

What the packaging may say accounts for very little. Macs from different time periods have different RAM specifications. What you installed probably does not meet the specifications for you MBP, hence your problems, To compound matters, Macs are very selective regarding RAM and some brands, even with the correct specifications, will not work in a Mac.
