In Topic: Random freeze and SATA LED on

Hi I installed Sierra. Having now stable system..

 

 

imac 12,2
 
1. install without boot flags..
 
2. Disable TRIM (in terminal)
 
sudo trimforce disable
 
reboot.
 
3. sudo rm /System/Library/LaunchAgents/com.apple.mediaanalysisd.plist
 
(For my motherboard)
 
DSDT FIX: (FOR SLEEP ISSUE)
 
Here is the fix. 
 
 
Dump your ACPI tables with F4 in Clover GUI. Open DSDT.aml in MaciASL (Boot with Installer USB)
Find RTC device and change all it's code with this
                Device (RTC)
                {
                    Name (_HID, EisaId ("PNP0B00"))  // _HID: Hardware ID
                    Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings
                    {
                        IO (Decode16,
                            0x0070,             // Range Minimum
                            0x0070,             // Range Maximum
                            0x00,               // Alignment
                            0x02,               // Length
                            )
                    })
                }
Thats it! Wake works like a charm. 

 

Had a freeze this morning after waking from sleep.  I was using imac11,3 and recently changed to macpro5,1; no change.  I did check out my DSDT and the device rtc section is almost identical to yours; mine was called RTC0 instead of RTC.  I changed to RTC and we'll see what happens now.

 

I am seeing reports of this problem happening on real macs.  It appears to happen on older machines.  I did come across a post saying it should be fixed in 10.13.2.  I'll see what happens once 10.13.2 goes stable and if I continue to have problems I will have to put together a new PC and retire this old girl.

Clean install didn't help the freezing.  It was bad a few days ago where it froze 4 times on me.  I've since disable time machine automatic backups and it's been stable since.  So far it seems time machine may be the culprit for me.

When do you have those slowdowns? I only have after login password.

I usually get the freeze after I wake from sleep and start browsing the web in chrome.  I had it happen again last night.  I was in chrome after I woke my computer up then everything froze.  Mouse wouldn't move or anything and the hdd led was solid.  So I guess disabling trim didn't help.

 

I did try a clean install of high sierra after the freeze last night and so far things have been good.

I've had this happen on my legacy system with a samsung 840 ssd on apfs and trim enabled.  Since disabling trim I haven't had any freezes.

Share please your EFI. My 960 won't load) only cursor on black screen


What fix you have in dsdt for gpu? 

I don't have any sort of fix in my DSDT for gpu.

 

I did forget about the AGDP work around that I am using.  I use imac11,3 system definition and an imac14,1 board-id.  If I don't do that I get a black screen.
