First of all, thanks for helping me with this. My problem is the following: I have a 13-inch MacBook Pro 2017 without Touch Bar. I bought an SSD (512 GB) to change the one I had (128 GB). I opened the computer, made the SSD change and started the operating system. At first it went well but now when I try to log in with my user, the computer restarts or stays with the status bar half full. I tried to start in recovery mode but I can not ... When starting in recovery in local mode, it stays in the apple logo where the status bar is and it never fills up. And in recovery mode over the internet, the bar fills up but then it restarts and it leaves me in the login screen and when I try to log in, the same thing happens before (the laptop restarts) I reset the NVRAM and also the SMC but it does not change anything. I tried to start in single user mode and it does not change anything either. I tried in verbose mode and it does not change anything either (only here I see the messages of the console) The weirdest of all this is the following: 1) When the laptop battery is at 5% or less, I can login but without plugging in the power cord and if I plug it in once logged in, the laptop will restart and return to the same thing as before. 2) If I disconnect the laptop battery and start the system with the power cord, it works well. 3) I have put back the old SSD but it happens exactly the same as with the new one. This is te output of the verbose boot: Any help I will thank you very much! Thank you!
