Make sure your Ethernet cable is connected to your Mac. This information helps a network administrator to identify your computer on the network while troubleshooting a server or router. Look at the Transfer Statistics section on the right. If the network is active, you will see an increasing number of sent and received packets. These statistics also display network errors and network data collisions. Collisions and errors can be caused by defective or misconfigured network equipment or interference caused by cell phones and microwaves.

Mark Waddington waddington1. Computer was working fine until two power ups ago it took a while to come online. Then we got a spinning wheel of death. I did a hard restart and got the blinking question mark folder. I tried the command R and the command option r.

Apple mac mini screen resolution

The flashing question mark means it cannot detect the hard drive. Did you happen to get any liquid on it or sit it in a puddle of water? You can try internet recovery or booting off of install media and going to the disk utility to check the status of the drive. October 18 by honeywillicker. October 22 by Jovie. Sandeep kurankirk. I found it running fine except for camera hardware and mic.

And sometimes it's laggy too. So I decided to downgrade. But don't work. Show's High Sierra to download and continue. Further it is also unable to download. Now again as per the apple service care, I followed the instructions to internet recovery.

What to Do if Your Mac Can’t Run OS X Yosemite

Still the same issue, takes me to the page High Sierra download and that won't do. Am unable to restore the os to its original OS which came alongwith it when at the time of purchase. Now I can't get to any recovery mode, or boot mode, none of the key combination work in this case.

Except these two options either questions mark page with all combination of hold press keys, or. Secondly a blank white page with mouse cursor when I try only "option" hold press while turning on.
