Morning all, I see someone else has had the same issue as me with one bug: the longer bootup times. Has anyone found out why this is? Also a thing that maybe connected to this is that once it boots up, all windows that I had setup the night before have moved around the Macbook screen and my...

Hey folks, After downloading High Sierra 10.13.2 update, I still can't connect to my file sharing (NAS) server. I've tried the "File Sharing Fix" that Apple provided (sudo /usr/libexec/configureLocalKDC in Terminal), and that was ineffective for me. I've called Tech support twice. :( Help...

Hi! I some somebody can help me with an incredibly annoying issue. About two months ago my MBP started to lose sleep: in about 40% of the cases in which I close the lid of the laptop, I guess it does not go to sleep. In about 60% of the cases it works as expected. When it does not go to sleep...

I've noticed some strange glitches recently. Images becoming pixelated messes, Netflix occasionally flashing a green screen during playback . . . Not sure if they're related though. I'm not very computer-savvy, so I was hoping someone here could help. Attached are a couple examples:

We always lose something. In the past we've lost the ability for Image Capture to sort by aperture or other EXIF data. With Sierra we lost the ability in the security settings to install software from unidentified developers without having to first go into the security panel (annoying). What...

Hello! I just recently purchased a macbook pro 2017 w/o touch bar a few days ago. Since the "time remaining" battery feature is gone, I use activity monitor to track how many hours I have left. When I checked, it said I has 3 hours left. My battery was at 90%. Is there something wrong with my...
