This i7 is coming up to its first year (which I think is covered by Apple?) and I *think* this maybe a memory issue? If it is, and my Mac is covered, then by a sheer stroke of luck, I decided to get Apple to fit the 8GB memory at the time of purchase (bad I know! and I don't usually do that) BUT that would mean that Apple fitted the memory upgrade and I haven't touched anything myself. However this time, I had the frozen screen saver, and a continuous 3 beeps which I've never had before in a loop? I then re-pressed the power switch on the Macbook and it rebooted fine and seems ok. I get a frozen screen saver which is normal, while the progress bar finds it feet back on power. I ran into an issue with my wife's MacBook Pro (Early 2011, 2.0 i7) where anytime it would go into safe sleep (i.e.My Macbook Pro battery had run down (it does quite a bit) so I rebooted with the power inserted. the battery went completely dead while the computer was asleep, causing it to resume from the sleep image file when power was plugged in) when I would bring it out of safe sleep it would make it 50% through the resume process and then I would get 3 tones/beeps separated by about 5 seconds and then repeating the same sequence. During that time the front LED would flash at the same pattern.īecause I had replaced the RAM (came with 4, wanted 8, but didn't want to pay the Apple price, so instead I bought from - they are amazing) I had suspected that maybe the RAM was bad or that it wasn't seated properly. I proceeded to re-seat the RAM and run a RAM diagnostics test ("rember" from Kelley Computing, ), the test passed. I called Apple to schedule a visit with my local Apple authorized technician, in Redding, CA). The technician booted up the laptop using the special Apple network diagnostics and all of the hardware "checked out" as just fine.

I decided that instead of calling Apple back, I would try fixing this myself since it appeared to be a software issue not a hardware issue. Because of the unique situation where the computer would start to resume just fine and then get the 3 tones, it seemed related to the safe sleep file (/private/var/vm/sleepimage). I had read that any time you put your mac to sleep the sleepimage file will get created, if it doesn't exist already. Some 16-inch MacBook Pro owners appear to have identified a shared issue suggesting the MagSafe 3 connector sometimes fails to deliver the expected charge. I decided to delete the file so that it would get re-created the next time the Mac was put to sleep. Now, I needed the Mac to go into "safe sleep" which is challenging, because normally this would only happen if the battery was completely depleated. Tip 4: Fix 'Mac keeps restarting' issue related to software. I learned a new terminal command to force the computer to always go into safe sleep. Step 1: Use macOS Recovery to start your Mac.

(Refer to step 1 in Tip 3.) Step 2: Use Disk Utility to back up your disk image to an external drive with enough free space. Step 3: Wipe the internal drive via Disk Utility.

Step 4: Install OS X and start your Mac from the internal drive. Where, setting hibernatemode to 1 tells your mac to always go into safe sleep.
By doing this I was able to force safe sleep to happen without waiting for the battery to be drained. After putting it to sleep and making sure the LED in the front of the computer was NOT pulsing (i.e. The power is truly off) I turned the computer on and it started to resume from safe sleep and it was able to finish booting as it should, no beeping occurred and all was well.ġ) when resuming from safe sleep, computer would beep three times every five secondsĢ) I used "sudo rm /private/var/vm/sleepimage" to delete the sleepimage fileģ) I used "sudo pmset -a hibernatemode 1" to force safe sleep when I close the lid and/or choose sleep from the apple menuĤ) Booted from safe sleep and confirmed it was working as expected.ĥ) To go back to regular safe sleep mode (i.e. Do not engage safe sleep unless the battery goes dead) using "sudo pmset -a hibernatemode 3"
