Hi guys, This is a recent problem which I cannot for the life of me work out. Essentially the sound balance on my macbook pro automatically defaults back to being slightly towards the right. This happens every time the computer goes to sleep or is restarted. I can change it back but it never...

Hi there. I have a refurbished Mac Pro 5,1 (mid-2010). I just recently grabbed a pair of Xeon X5690 SLBVX 3.46GHz chips and had a friend install them. Since the install, my fans have been running full-tilt - resetting the SMC and PRAM has no effect, and I took off the heatsinks to make sure...

Hi All, I have MacBook pro late 2011 model 13 inch. My MacBook charger was getting old so recently I bought another one. I thought my older charger wasn't charging but I used to see the green light whenever plugged in but I thought its not working so bought new one. Now after buying new charger...

As of a week ago, my iMac will either shut itself off when asleep or, if closed down properly, will not start up when I press the power button the back. This behaviour is intermittent. It will start up if I reset the SMC by taking the power cord out, wait 15 secs then plug it back in. So...

I was using my mid 2013 Macbook Air 13inch yesterday and it died while using (at full battery). Plugged her in and she came back to life, had 98% battery. She then up and died again 10 minutes later, straight to black screen, no light on apple logo on clamshell. Pushing the power button does...

As the title says, I have a mid-2009 17" MBP which has developed a strange problem with booting and (sometimes) waking from sleep. In a nutshell... When I press the power button, I can hear the bong and the initial seek of the DVD drive. Most of the time, the system drops into what appears to...

I have a mid '14 MacBook Pro 15" that will not boot due to a (1) typo I made in the nvram's boot-args, and (2) inability to reset the nvram. I suspect this is because my machine has a dead firmware battery, which it may have always had- I've always noticed that exhausting the main battery would...

ok, ive looked into this issue and have seen many threads (including here on MacRumors). almost all responses point to a battery issue. I have a 2011 Macbook Pro8,2 @ 2.3Ghz. About 2 months ago it started powering off randomly. as if you removed all power sources from it. As of recently the...

Good evening I got a used macbook A1181 2006 1.83 Ghz (32bit- non Estar) and there was a problem, at the begging, on the battery charging issue. I opened the macbook and I found a wrong battery connector / sleep SW component. To be clear: My logic board supports this (Non Estar- 20pins)...

My computer just started doing a baypass smc . I would like to know if there is some way normal start your computer

I'm trying to troubleshoot my macbook Pro -17" and am looking for a schematic and boardview or parts placement diagram for logic board 820-2610-A dated 2009 on the PCB. Currently the green LED on the adapter is on when plugged in, and the battery light appears to be on and charged. The laptop is...

Hey everyone, so a little backstory on the laptop before I explain the problem. A couple of months ago, I took it to Micro Center to get it fixed. They concluded that the logic board had to be replaced and maybe the top case. The repair was almost $1,000 so I just bought a new laptop. It has...

Came home lost month to my Macbook whirring away for no discernible reason. Happened again a day or two ago, and then again just now. Also lately it has been waking somewhat slower from sleep than normal. Sound like stuff an SMC reset would take care of? Looking at the support article, they do...

Hi there, I have a really simple problem that I want to solve the very hard way. I have a mac mini 5,2 (radeon graphics) I bought brand new in 2011, and it get replaced logic board in 7 month or so under warranty. It was almost not used since. Booted it yesterday after a year and got a huge...

Hi, i know this has been asked a million times before. but i just need some advice. i spilled water on my Macbook Pro (early 2015) that i bought in may. I immediately turned it upside down and it did power off by itself (Which it is supposed to to prevent damage for as far as i know). The...

Hi there, I have been scouring the net for a solution to my issue, and none of the responses have worked so I hoped I might be able to get some new advice. I opened the lid of my A1398 (2012 Macbook Pro 15" Retina, 256gb SSD) this morning and the trackpad and keyboard had stopped working. I...

I've been researching about SMCFC and I still see questions that don't have a defined answer. I'm wondering if you guys can help me answer some questions or recommend me an app that does what I'm looking for. 1. When SMCFC is on, the default is at 2000RPM. Let's say the mac starts getting...
