Hi everyone!
I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.
I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...Today, 08:54 AM -

Right SIDE usb.c port charges and transfers data without issue, two left side uSB c ports charge but do not receive or see data. Was liquid damaged, and repaired significantly and thought we were in the clear but appears this is the last issue that is rearing its head. I am trying to locate the RETIMER chip that communicates the DATA TX/RX but I cannot seem to find it on the schematic or maybe I am just so tired my eyes wore out lol. Any help would be great.05-29-2025, 10:35 AM

Hello, the Magsafe connector of the above Macbook was defective(burnt pins). It is located on a small DC-IN board labeled 820-2361a sitting in the top right corner of the macbook, connected to the main PCB with 5 separate cables.
While replacing the magsafe, I must have unsoldered and lost a small SMD Resistor that is silkscreen-labeled R1 on the solder side(opposite of the magsafe and ferrite filter). It carries the 1bit-bus to the Amber/green LED driver chip in the Magsafe plug, and without connection to the 1-bit chip in the plug, the macbook won't charge.
¿Can anyone please provide... -
Hi guys.
May I charge this model with 60 W charger?
I know it requires 80 W to charge, but don't want to buy one.
If it specifically requires and 60 W can damage macbook and vise versa, I guess I will have to buy 80 W one....
