My MacBook Pro becomes extremely hot on sleep mode

2 years back while upgraded to OSX Sierra of My Macbook pro Retina 13" late 2012, I noticed it heated up & almost burnt while on sleep mode with the monitor closed. I had to play with for a long time & found the culprit is the Sleep hibernate mode. While with OSX Capitan, its sleep hibernate mode was 1 but after upgrading to OSX Sierra, it automatically became hibernate mode 3. I tried to change to 1 using terminal but it did not allow. Therefore I downgraded to OSX Capitan. But with Capitan, e.mail was troublesome. After OSX High Sierra is launched, I again upgraded to OSX High Sierra. Everything is nice with High Sierra, e.mail also very organised but again my macbook pro become very hot while on sleep mode. I checked the sleep hibernate mode, it is again 3. I tried changing to 0 & 25 but still same heat issue, I could not change it to 1. Any one is there who can help me how I can change sleep hibernate mode to 1 instead of 3? I am sure it will be ok if I can change to 1. I contacted apple service centre but they have no idea what to do. Awaiting support from the apple community please.Regards, Dr. Mostafa

MacBook Pro (Retina, 13-inch, Late 2012), macOS High Sierra (10.13.1)

You can downgrade:

make enough backups,

then in the Internet Recovery Partition (CMD+R+Alt/option),

you can first format/erase the disk in HFS+ (Mac OS extended (journaled)),

then install OS: it will install the original OS that it was delivered with. Probably earlier than ElCapitan, depending when you bought it.

(After the restart you can upgrade to ElCapitan with the downloaded installer).

It will take some time, everything is slow and it has to download the whole OS.

The Apple hardware test is nothing in comparison with the AHT that Apple uses.

I suggest to test your Ram now first: test your Ram with Rember.app, it takes some time: when there is an issue there is an issue, when it says all Ram is OK, there still is a slight chance that there is something wrong:

Hi Lex, I am on Internet recovery now, but when I press to erase disc, Format options are only APFS, APFS(encrypted), APFS(case- sensitive), APFS(case -sensitive, encrypted), I did not find other options for installing maverick. Any help please?

Hi Lex, I successfully downgraded to Maverick OS X version 10.9.5 & I changed the hibernate mode to 1 & my macbook pro has calm down, no sign of heat in sleep mode or while the lid is closed. I already organised everything except there is no bookmarks for Safari- it was in iCloud but now I am not finding any of the bookmarks. I have backed up but I do not find any way to import those Safari bookmarks- Can you please help?

( If you had exported the bookmarks before downgrading it would have been easy ).

1. Do you have a TimeMachine Backup?

If you have a TimeMachine backup:

In Finder->HomeFolder->Library->Safari select the folder "Bookmarks.plist"

Then in click TimeMachine in the top menubar, TM opens with the Finder window that you had set,

then go back in time to just before the downgrade,

select the Bookmarks.plist if it is not already selected, click "Restore".

2. If you do not have a TM backup, but you have a backup from before the downgrade:

Open Finder, goto the backup, select the Bookmarks.plist (in the location above, but in the backup), then copy it to the your documents folder; then in Safari import it. Or if that does not work, write the recovered bookmarks.plist over the one that is in the Finder->HomeFolder->Library->Safari folder.

Hi Lex, once again I am here. After I downgraded to OSX Capitan, I could change the hibernate mode to 1 & my MacBook pro became just cool, no more hot on sleep mode. I could also recover the Safari bookmarks but new trouble started- Safari all on a sudden became hang or closed, e.mail also same. I understood apple will not allow me to stay cool with Capitan. Finding no other hope I again did fresh installation of High Sierra. After that I had to be careful so that i never leave it on sleep mode as I started to be hot on sleep mode or closing the lid. I also tried 3 to 5 SMC Reset & after about 42 SMC Reset, my MacBook pro became gentle, obey sleep command & no more hot on sleep mode or closing lid. I took a deep breath & sigh although its after a long long tries. So what I learnt from here that one has to be very patient & try SMC Reset until the power related problem is over. Anyway, I am thankful to you for your kind assistance to me time to time. I am also happy as I am able to use my MacBook pro confidently as before.

What happens if you set the hibernate mode to 0 (a sleepimage will be created anyway in HS)?

Incredible. Clean as a whistle. The WindowServer is a high.

What happens when you quit Safari before going to sleep?

When you start in SafeMode (holding the Shift key) and you let it go to sleep?

I advise to go to Apple and let it diagnose. Something is wrong, likely hardware.

Hi Lex, is there any possibility to downgrade? I tried but because of APFS, after downloading Capitan, it did not instal. Any suggestion please?
