A couple months ago, I started to see some very small stain spots on the bottom of my MacBook Pro early 2015 screen. It's very annoying to see while I'm using it. When the screen is turned off, I see it as in the picture below. But when it's turned on, I see it as very small water-ish drops. I tried to clean it using water, screen cleaner, and even alcohol, but it didn't go away.  Also that area doesn't feel as smooth as the unaffected area. So, I think it's on the outside of my screen not inside.  Have you ever seen this before? Any suggestions on how to remove it without the need of replacing the whole screen?

I try to clean my mid-2015 Macbook Pro with Retina display by wiping the screen with a damp cloth and then immediately drying.  However, there seems to be left some residue/streak marks, which look very oily. Sometimes these disappear after a few minutes, but they are still very unsightly, and a bit worrying (is there something wrong with my screen?)  I'm wondering if there are other cleaning techniques which avoid this issue, or whether this is completely normal behaviour.  Thank you!

When I first got my MacBook Pro, it took less than 30 seconds to start up. Now, after several months, it takes about two minutes to startup and I can tell that it is not as responsive when using some applications (it was fast before).   I am wondering if it is because I'm not shutting it down that causes the lag during startup.

Several weeks ago a darker spot appeared on my screen (as seen in the attached picture, it's right under the "Super User" tab) and it looks as if there was some liquid behind the screen. When I physically press it, it doesn't change its shape and it didn't change its shape since it appeared (around 2 weeks ago). The spot is visible especially on white background and is very weak with black background.  I tried blowing hot air on it and rubbing strong magnet (from a hard disk) but neither helped nor made it change its shape.  Do you have any ideas what could have caused it? Additionally, do you know how could it be fixed besides using my warranty? The laptop is 4 months old, Asus UX530UQ.  Thanks

I'm far away from civilization thats why I need your help guys. My problem is: MacBook Pro 13" early 2015 is not turning on and charging and the trackpad is also dead.   Charger's LED does not shine by any light(red/orange/green) . But I tested my charger with another MacBook and charger is working. I tried to connect another charger. First 1-2 minute I can see green light and then LED turns off. Trackpad is not react to any action (like double click). Right now this is just some plastic area Turn off and turn on battery connector also didn't help me.   The laptop did not receive any damage and was not flooded with water. Day or two before I got it from safe and checked my email then closed it and put to the safe again(hotel standard safe) (everything was okay but I didn't remember battery charge percent at that day) then I open and figured out that MacBook is dead.

MacBook Pro (15-inch, 2016) with 2 USB-C to HDMI adapters. The setup works great if I start up in that configuration.   If I connect the adapters while the machine is running or simply sleeping, one of the monitors will never get a signal and stay in low power mode. The OS sees the monitor, it shows in the display arrangement settings and I can move the mouse into it, but until I restart, I can't see anything on it.  Once I have restarted I can let the machine sleep or whatever, and the display still works unless I disconnect the adapter. As soon as I do that a restart is required to use it again.   Using MacOS Sierra (10.12.4)  Using this adapter:

So yesterday I dropped my iPhone into the toilet, it was literally submerged for less than 15 seconds and after taking it out I left it in my airing cupboard overnight to dry. Today the phone seems to be completely functional other than a very dark screen (changing brightness won't help).   Was wondering what the best course of action would be and if this is fixable.

I am, like so many other graphic designers, very excited about the new MacBook 15" with retina display. But there is one thing that I really am concerned about. With 4 times the pixels as on ordinary screen, how can we be sure, that the preview of an image, is what we really get?  When images are optimized for web usage, how can we be sure that the optimized image, is what the end user (with a non-retina display) wil be seing?

Recently, something went wrong with my Macbook Pro 13&quot; 2019 model's display. About 1.5 inches (in length) of my display went completely black and there are some vertical lines on the edges of this black portion. It appears to be a hardware issue.  I was wondering if I can do something so that my entire screen appears in only the part to the right of this black portion, until I can find the time to give my laptop for repair. I know I can just rescale my window each time, but I don't want to keep doing that every time I open a new window. Can I use software to remap the entire display area to a smaller section of a physical display?

This is not a problem at booting up. For a couple months now I'll be using my laptop when suddenly the screen dims to about 50% of normal. According to the brightness indicator the brightness is all the way up; I can make it dimmer, but not as bright as normal. The dimming isn't super even either, there are small areas of the screen that seem darker/brighter. In the past the problem easily goes away if I close the lid and reopen it... but now it's happening a lot and sometimes going completely black. Is this an easy/cheap fix? I'm traveling and can't do it myself. Is it worth bringing to the Mac store?  Thanks!

On the screen on my MacBook Air, there are some little square marks from the keyboard.  Are they permanent, or can I clean them off? How can I prevent this from happening in the first place?

I have a larger, external monitor connected to my MacBook Pro and have arranged it such that the dock is in the external monitor (via System Preferences > Displays > Arrangement, by dragging the white bar to the larger screen). This works fine, except for the fact that every now and then, the dock will suddenly shift back to my MacBook screen, but when I open up Displays to change this back, the white bar is still on the external monitor. So I have to drag it to the smaller screen, and then drag it back to the external monitor.   It's a minor issue, obviously, but I've noticed that it has been happening more and more frequently and it's getting quite annoying. Perhaps there's something I've been doing unintentionally for this to happen?   I'm using Mavericks, 10.9.5.

I am somewhat new to caring for Macs, but one has been left in my care and I have not been able to restore it to working order yet. Here are the symptoms:   The MacBook Pro would hang with a "white screen" during the boot process. A bit of boot splash would show up, but the gray background would at some point just hang. Booting recovery mode did not work, as far as I remember. Boot from a Ubuntu 14.04.2 USB stick works, provided one attaches "nofb nomodeset" to the kernel commandline (though I put that one down to insufficient driver support). I have no idea whether or not these usually work out-of-the-box. Using parted from the aforementioned stick, I was able to see three partitions, one EFI Boot, one large main partition and one labeled Recovery. It seemed strange that the recovery was recoognized as HFS+, as I expected, but the "main" partition was not mountable and did not show a filesystem type. I also discovered that the drive in question was an OCZ Vertex3 256 GB, which I assume is not standard? The previous owner could have upgraded it. At this point, I decided to wipe the drive and try with a fresh installation. I removed the SSD from the MacBook, pulled a full disk image from my desktop just in case (which went without any read errors) and used hdparm to do an SATA enhanced erase, leaving me with a "fresh" disk. Then I put it back in. I started internet recovery, which loaded, showing me the global and everything. Afterwards, it rebooted, showing me the Apple Logo. But then I run into the original "white screen" again. I've tried resetting the NVRAM on boot, which succeeded because it turned the boot chime back on, but even then, running internet recovery again just causes it to hang on the white screen. There seems to be either very high CPU or GPU usage on the white screen, as the fans start wailing pretty intensely, also the body gets very hot in a very short time. For funsies, I installed Ubuntu onto the MacBook, which works (after smoothing over a few hiccups, fortunately I have lot more experience doing that). Recovery mode (Cmd+R) and Apple Hardware Test (D?) I have not been able to run. The former suffers the same white screen issue as described above.   Currently, my only vague guess is a GPU issue, that may be circumvented by Ubuntu by using the not completely feature complete open source radeon drivers. But that is a wild guess. Any input is appreciated.

My MacBook Pro shows a grey screen with a flashing question mark in a folder. I tried connecting it to an older MacBook using firewire cable. I restarted the Macbook Pro in Target Mode. Now I see Thunderbolt and Firewire icons flashing and moving in a grey background. There is a green power icon at the bottom as well. I am not an expert even though I have been using Macs for ages.  How can I fix this issue so I can recover/backup things in the MacBook Pro hard drive?

Alright so i spilt a bit of water on my keyboard while back. It was very little so i didn't really try to do anything. However a few minutes later i realised that some of the keys on my keyboard won't working very well. So I switched the laptop off and kept it upside down. I turned it on after half an hour and although things have improved, I'm very  concerned...  For example, the A key doesn't work. Pressing 1 or 2 types out both etc.   Rest everything seems to work as usual.   Do I need to do anything except wait this out?

Old computers were using CRT monitors and when an image was continuously displayed on the screen, it became marked. So, screensaver where invented to avoid screen burn-in.   Laptops and modern computers almost all uses LCD display now and, AFAIK, they are not affected by this effect.  So, should I completely deactivate this feature and use power management instead or I am wrong?

How do you turn off the MacBook Pro’s display with the lid open while using an external monitor on Mac OS X 10.10 Yosemite?  All the previous methods—such as the one’s —that have worked on Mavericks no longer work on Yosemite.  Does anyone know the way to do this on Mac OS X 10.10 Yosemite? Turning down the brightness is not the same as turning off the display as the GPU still sends a signal to the internal display and the external monitor.  These were the terminal commands to achieve this on Mavericks:  Enable  sudo nvram boot-args="iog=0x0"  Disable  sudo nvram -d boot-args  Anyone know how to achieve this on Yosemite?

I have a a MacBook Air that works fine except popping up a shutdown dialog if left untouched for a couple of seconds (seems to be a consistent duration around 3 seconds or so). Hitting Cancel or Esc prevents the shutdown.  If I keep fidgeting around with the keyboard or trackpad, there's no shutdown attempt. I can even place something on the Fn key to keep the OS from shutting down.  It seems like some inactivity timeout etc. gone awry.  When taken to the Genius Bar for initial assessment, the guy there said it was probably the power button needing a replacement. But, I don't think this is the case, as the power button is functioning normally: I can still press it to explicitly initiate a sleep/shutdown.  There's a chance this was triggered by water damage. There was a recent water spill incident to which I acted quickly by turning off the machine + turning it upside down + not using it for a long while + keeping it in a box with rice to absorb any leftover humidity. But even if this is a water damage, I can't imagine a damage that manifests itself with this very narrow malfunction of wanting to shutdown on a short period of in activity. Absolutely nothing else seems to be wrong with the machine.  Any pointers? Any things I can try to (a) diagnose the root cause fix or workaround the problem?
