The MacBook Pro 13" from my client is falling so the hard drive was no more operational.
Then replacement was very easy thanks to the iFixit guide, just a real plaisir to do it. Everything is really well explained withs text and photos.
Just it seems to me that the torn T6 was the wrong one by me, I used the T5. Unfortunately, I have no photo because the Mac is again by the client now, sorry. Next time.
