Mac safe mode boot fail

I'm not sure if that was the reason why the second I open it, it won't boot successfully.

I'm worried about the files I just transferred from my phone but thankfully it opened so I'll go ahead and retrieve them back for safety. Thanks again! I followed the power cycle reboot steps and got my mac to give me signs of life and then when it died in the middle of boot I restarted the process and plugged the battery in the middle because I only have a 60w power supply and needed an 85w. I used the battery as a wattage boost in the middle and got my computer back up and running. Thanks for the guidance. My Mac Pro late , non removable battery behaves strangely.

It does not switch on at all. Battery shows fully charged when I check by small side switch. Now, If I remove adapter connector, Mac starts up. But no chime. Before it completes booting it shuts down. Restarts on its own after sometime. On restarting same thing is repeated. Any suggestions please Black screen, L-type chord shows a charge going on orange light , fan whirring. No other signs of life. No start up chime, no matter how many times I hard power down and restart. It's a MacBook pro with a non removable battery.

Hi Fennelly. I have the same issues right now. Did you manage to bring back your computer back too life? Holy Bologna!!! I was convinced my MacBook Pro was toast. The special Poeer cycle seemed Compliments on the well structured and informative guide! Started using a Macbook Pro Md for a week or so now, when it just turned off. At the istore they performed a SMC and run a diagnostic check - proclaiming all is fine. A day after it happened again. Thank you kindly.

Great guide, I have no Mac experience and was able to repair my son's Mac using your guide. After hours of trying everybody else's suggestions I fixed me problems with your pointers!!! It took many layers of fixes but eventually sorted out my MacBook. I luv u?????? You are awesome! I reset the PRAM and it booted up quickly.

Worked like a charm. You are the best. Thank you. The first solution worked for me!! The fan seems to be a lot louder.. But my MacBook is up and running. Thanks so much, Jessica and to Victor Clausson for the "special power cycle" tip. Thanks Jessica! But even after all the El Cap troubleshooting, I've still been stuck! Then, a little comment from you and I was digging into RAM at the same time, but getting no love: It's the memory sticks.

Thank you, thank you, thank you! Mark Alan E http: I thought you were nuts. Unplug the power and hold down the button? Reattach the power and keep holding the button down? What was that possibly going to accomplish? Have appt Apple Store in 1hr!! Been having battery problems within my Apple Care but store refused to do anything; kept doing diagnostic, all extras……????????

I didn't remove my partition with the OSX install - I just can't access it! I don't know what to do. I have replaced the old keyboard thinking it might be problem with the new one. Hi, I'm happy all other users solved their problems with Mac.. But, My problem seems a bit complected.. But still get White Screen after chime Sound Non of the startup combinations or shutdown work Any suggestion would be great Thank you.. Three days ago, I plugged the Macbook early into the socket to charge.

The next day when I turned it on - nothing happened. No chime, no screen, nothing. Took it to Mac Genius which was a waste of time, took it to an Apple approved repair shop, they said the keyboard was clearly full of water impossible , had a technician visit the house and test, doing all the magic tricks you can do to wake up a mac, nothing worked - everyone said it's the logic board.

I have had this Macbook purchased new only 2. It didn't make sense that this essential and most expensive part of the MBP would die so soon. I had suspected the battery as responsible for some time for other issues erratic track pad for example. I backed up the computer, turned it off - no problem rebooting at all. And in fact the computer is working much faster now. I will have it totally checked out and replace the battery 38 euros.

Hope this helps people with similar issues! Thanks for your sharing, I had have same issue with you. I followed your steps. And ahaa!! That is so awesome!! Its always Battery Issues with Apple Products. I gave up!! Constantly going to Apple Store is annoying especially talking to Genius staff is useless. Thanks so much! I'm grateful for your help! Thanks a lot!!! Thanks again. Suddenly Macbook Pro bought in would only turn on , and run for about 2 minutes, then shiut down.

I also made an external usb installation media with DiskMaker on another computer, but when selecting"Install OS X" from the usb and selecting the internal HD for the installation, I now get the message "This disk is used for Time Machine backups" - apparently because it is indeed a copy of my backup disk!

Holy crap! Power cycle worked! Thank you it helped me a lot and the trick with the power cycle worked for me. August - 15" MacBook Pro What happened: Starting up your computer and making it run in Safe Mode is also known as a safe boot safe boot is how your Mac starts, Safe Mode is how it runs. A safe boot also checks through your startup drive to make sure there are no problems there.

A fault in your system like corrupted boot sector might be preventing you from using your Mac at all. By booting in Safe Mode, your Mac can work with macOS core processes to get back into the system and identify problems, such as floating extensions or rogue applications, that you can then remove. When your computer is prompted to perform a safe boot, it will perform a number of tasks before you can use it, which include:.

Once your Mac is running in Safe Mode, some applications will no longer be available. You can manage the list of startup applications manually, removing the potential buggy apps one at a time to see if it affects the performance. There is still a problem though. To diagnose your Mac more precisely, we recommend performing a full scan with some dedicated Mac cleaning app.

As described above, CleanMyMac is our favorite you can download this app here for free. Note that it may take longer than usual to boot your computer: You will not have to hold the Shift key when the computer restarts, simply log in when prompted. To find your boot mode, click on the Apple logo in the menu top left and select This Mac.

Choose System Report, then Software, and from there you will be able to see whether you are in normal or safe mode. Your performance speed will change. Typically macOS will run slower when it is in Safe Mode due to the reduced processes, but if you have noticed some serious lagging this may be improved by the faulty applications being restricted. Running your macOS in Safe Mode is normally used to troubleshoot glitches that you have noticed, such as lag, crashing, or spontaneous closures of applications.

You should try to use your Mac as you normally do so that you can see if the issues have disappeared in Safe Mode or are still there. It should then reboot as normal, hopefully with improved performance.
