The concern isn't really when it's in the fridge but when you take it out. The cold laptop/parts will pull the water out of the air AFTER it's taken out of the fridge, even if it was in a plastic bag. Think of a glass of water, it doesn't 'sweat' when it's in the fridge but you take it out on a hot day and it does. The other concern is, depending on the ...

As you suspect, it is not a very good idea. The cooler air inside the fridge can quickly condense the vapor normally found in the air, producing little droplets of water on the coolest parts (such as the motherboard). Even if you find it effective, it may result in damage to your computer. I simply suggest you not do it. Read USGS website for more ...

I "solved" this problem using https://github.com/jakehilborn/displayplacer. If I connect my hub and the monitors are incorrect, instead of having to rotate screens or reconnect cables, I can now run a script (via a hotkey) to resolve this. First, make sure your monitors are in the correct configuration. Then install displayplacer and run it. brew tap ...

This is what worked for me on my Macbook Pro using Yosemite (10.10.2) and the official RDP client from Microsoft while connected to a Windows 2012R2 server: fn+control+alt+delete

Another possibility is that you had a hard shutdown and the postgres process died without cleaning up its pid file. This happens to me when my laptop's battery dies. This solution is not for a production system, and you should really make sure the postgres daemon is not running, but I use my laptop for coding and I'm not worried about needing to regenerate ...

Yes! I have 4 external monitors and this drove me nuts until I figured it out. Play around with moving the "top" bar between screens in the Arrangement window. Assign it to different screens and you will notice it will solve your issue once you find the "right" screen. I can't remember why that worked, but it did. Alternatively, you can also drag one of ...

As others already said, you're killing your laptop with the condensation. The water will usually not lead to a short circuit immediately, but instead lead to rust buildup first before the final shutdown after a couple times in the freezer. Better solutions: You say the laptop is still under warranty: Use the warranty. Bottled air to clean the fans without ...

After hours of searching the internet, I discovered how to enable virtualization in Boot Camp. Instead of booting into Windows by holding the option key on startup, boot in to OS X. Then go to System Preferences -> Startup Disk and choose your Boot Camp partition. The computer will restart and boot into Windows, with virtualization enabled.

I have a similar overheating problem with my MacBook. The fan was always spinning away. My solution was to freeze an ice pack (I think that's what they're called). Wrap it in a tea towel (to absorb moisture) and sit my MacBook on that. After a few minutes or so, the fan stopped and my MacBook was happily cooled.

I also have this problem. It seems to be more prominent after waking up from sleep. One temporary fix I use: create a new space in Mission control, drag all the Chrome windows in the "focus-hog" space to the new space (in Mission control, click and drag the Chrome icon up onto the new space), and then drag them back. This seems to reset the behavior for all ...

If you like terminal, then you can get via below command system_profiler SPDisplaysDataType |grep Resolution For example >system_profiler SPDisplaysDataType |grep Resolution Resolution: 1920 x 1080 @ 60 Hz

For me it's based on which cable I plug in first, even when I plug them into the same ports. I'm using two HDMI cables. If my screens end up swapped, I just unplug one of the cables and plug it back in. If the screens are still swapped, I unplug the other one and plug it back in. The screens will both flicker and they'll swap back to normal. This seems like ...

This is now supported through a tool that edits charge level in SMC: https://github.com/davidwernhart/AlDente I have it installed on my Macbook 12 (2016 model) it's sitting at 70% plugged in.

I have used a piece of receipt from shop. It is thin enough to fit. The goal is to close middle connector. It is possible to close also 2 connectors at the left or at the right. For example close 3rd, 4th and 5th connectors, but leave free 1st and 2nd or conversely.

If you'd prefer a response regardless, try this: (system_profiler -detailLevel full SPBluetoothDataType | grep "LMP Version")2>/dev/null If it shows a version of '0x6' or greater, BT 4.0 is supported. There is another similar post here.

You can take a look at the Link Speed under the Intel 5 Series Chipset section. SATA levels are named after a number (1, 2, 3) and also for their speeds. SATA 1.0 is known as SATA 1.5Gb/s SATA 2.0 is known as SATA 3.0Gb/s === Your computer supports SATA 2.0 SATA 3.0 is known as SATA 6.0Gb/s "Link speeds are the theoretical maximum speed at which data can ...

I did some more research, and came up with a temporary solution. Not the best thing to do, but it certainly worked for me. So whoever has the same problem, do this: open Automator, select Application add a Shell Script item enter the following command in it: ping -i 0.2 192.168.1.1 (or whatever the IP of your router is) Just save the app, start it and let ...

USB 3.0 often has blue lining inside the port. If you want to know specifically for your macbook air, go to apple support page http://support.apple.com/specs/ - Click on "Browse by Product" and enter your Macbook Air serial number. It will show you the Tech Spec specifically for your Macbook Air series, and the tech spec will tell you what USB you have.

The condensation that could form when you remove the laptop from the fridge would make me worry enough to not to do it at all. I have seen people that have drilled holes in the body for cooling and other crazy things like that in the past. Maybe it's time to upgrade the machine? EDIT from comments: Stop using Google Chrome for Mac. It seems to consume far ...

Caffeinate For example: caffeinate -i rsync -avz someuser@somehost:somefolder /some/local/folder From the man page: EXAMPLE caffeinate -i make caffeinate forks a process, execs "make" in it, and holds an assertion that prevents idle sleep as long as that process is running. It can also be used for situations like "don't let ...

It's not ideal, but here's a solution. To prevent the laptop from sleeping when the lid is closed and you're running on battery, run the following commands: sudo pmset -b sleep 0; sudo pmset -b disablesleep 1 To re-enable laptop sleeping when the lid is closed and you're running on battery, run the following commands: sudo pmset -b sleep 5; sudo pmset -b ...
