I was lucky that two of my friends have the same setup and we just tested this.
#Macbook pro 3 beeps after running infinite loop upgrade#
The beeping still persists.Īnother update: we reproduced the problem with 2 other 16 inch pro models (these are the base models with only upgrade SSD to 1TB). Has anyone else with the 16 inch M1 Pro (or any other MacBook) noted this issue (I dont usually shut down my laptop, so it was entirely by coincidence that I found out about this)?Įdit/update: I ran the apple diagnostics at startup and it says no issues found. I only noticed it by accident last night and had a few minutes to mess around with it and find out that the other laptop does not show this behavior. I am not sure if this is impacting the charging of the laptop or not. It does NOT occur with my 16 inch M1 Max, there is either a single chine or no sound at all. It is entirely reproducible and happens every single time I do the above. If this sequence is done there is a continuous beeping noise that occurs every 5 seconds or so (it sounds like the charging chime that should only occur once, when the charger is connected). I have a 16 inch M1 Pro and M1 Max, the issue only occurs with the M1 Pro and only happens when the following criteria are met: 1) Computer has to be SHUT DOWN (so not just closing the lid) 2) lid is closed 3) fast charger with MagSafe is put in place. So far, this behavior only occurs if your laptop is at or blow 60% charge, you have hit shut down, closed the lid, and attached the mag safe charger (there might be other combinations that yield the same thing, but this is what made it happen on my end). TLDR: The 16 inch M1 Max or Pro, have a behavior where if the battery is less than 60%, the computer is shut down, the lid is closed, and the MagSafe charger is connected they start beeping intermittently at regular intervals (about 5 seconds between beeps) and the charger light turns on and off repeatedly (as opposed to staying a solid color).
