When you’re booting your Mac from the recovery partition and are planning to reinstall OS X, you might be met by the following message:

An error occurred while preparing the installation. Try running again

Time Fix Mac Os X

Shut down your Mac. If you can remove the battery or disconnect the power cable, do that. Wait ten seconds before proceeding. If you cannot disconnect the power, use a keystroke instead. After your Mac shuts down, press Shift + Control + Option on the left side of the built-in keyboard, then press the Power button at the same time.

Now, if you haven’t used your Mac for a while, the error might be caused by an incorrect system date setting. You can check this by going to utilities and opening the terminal. Once in the terminal enter the following command and hit return/enter:

  1. Is there an alternative for the timeout command on Mac OSx. The basic requirement is I am able to run a command for a specified amount of time. E.g: timeout 10 ping google.com This program runs.
  2. We probably want to include the macOS Sierra Beta 4 time fix in Go 1.7 final, despite claiming that rc4 was the last change. Unfortunately we found out about the Beta 4 kernel change about 15 minutes after releasing rc4.

The result of this command will be the date that the system currently has been set to. For some reason, it might have been reset to 2001, in which case we need to set it to the right date. To do this, we enter a new command. This command will be entered as follows:

Every bracket should be replaced with a two-digit number based on UTC time. Below you see what the command should be for your current time and date – . To avoid trouble with timezones, we will use UTC time instead (). Which means, you can just enter it exactly like this:

Enter the command and hit return. You can then check if it was set correctly by running the first command again. If the date was wrong, it was likely that which caused the error, and after you quit the terminal it should be able to install OS X just fine.

TimeFix Mac OS

Time Fix Mac Os Download

Most of us do dual boots with our hackintosh. Windows and OSX , but one thing we realise is that when you fire up Windows. You realise the the clock is out of sync and you decide to let windows automatically sync with time servers and then it gets fixed. You said that it could be a mistake and you carried on with your work . The following day when you boot up to OSX , you’ve noticed something odd – the clock is out of sync. Its like a demon that is changing time. You decide to fix it up the same way and so the cycle continues. You’ve tried everything that you could to get these two OSes clock to work in harmony. Well , fear not – Today , I’ll show you couple of ways to fix this issue. From the straight forward method to the complicated method. For each methods , I’ve described here – there are both advantages and disadvantages. Don’t worry , I’ll list them all. If you’re curious why time gets out of sync , then stick around and read the whole thing
(more after the jump)
The easiest method – Boot Camp Method
Advantages :-

  • Well it just works
  • Its suitable for brain-dead retards (nah I am just joking , what I meant to say is that umm its suitable for the less tech-savvy)
  • Works with Windows XP , Windows 7, Windows Vista and just about any Boot Camp supported OS by Apple !
  • Makes you feel like having a Mac 😛 (you could proudly say “Hey peeps , I got Boot Camp running on a Hack”)
  • Gives you the ability to read your Mac partition while in Windows (thanks Mushishi)

Disadvantages :-

  • Increases Boot Up Time – On hacks for what-so-ever reason it pauses for a while. I was told that it looks for EFI support , thus the reason why it pauses
  • Bloatware (it installs other Apple Boot Camp softwares such as Keyboard support , Apple mouse support). Some folks hate it very much

Method :-
1. Insert your MacOS X Installation disc in Windows. When autorun prompts , simply run the Boot Camp installation wizard. If it says that its not a Mac or something , run setup.exe manually
For 64-bit Users (Windows 7/Vista) – Here is a great tutorial on how to install Boot Camp drivers on 64-bit PCs. Generally if you run the installer , it says that its not supported. However this guy has managed to find a trick on how you can get it to install
Reboot and everything should be fixed and the time should show up correctly on both of the systems


The Method for Adventurous – Registry Fix
Advantages :-

  • Its clean as in no additional programs are needed to get it working
  • It extends your knowledge of Windows Registry
  • Chuck Norris prefers this method 😛

Disadvantages :-

  • It only works for Windows 7 & Vista and not for Windows XP
  • Messing with Registry can be a tedious task for some especially those who are not comfortable with messing stuffs such as this

1. Firstly fire up Registry Editor by typing regedit.exe in Windows 7/Vista Search Bar. If you have UAC enabled , you should get a prompt. Simply hit yes.
2. Now Navigate to this key , to do so simply keep on double clicking the folders till you come across to this
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlTimeZoneInformation
If you are not sure , please click on the picture so that you can have a larger view of it.
3. Right click on the empty space right below ‘TimeZoneKeyName’ and create a new Dword (32-bit). On 32-bit versions of Windows 7/Vista , you will only see D-WORD .
4. Rename the new DWORD as “RealTimeIsUniversal” (without quotes and its case-sensitive) .
5. Double click on the new DWORD and change its value data “0” (thats a zero) to “1” (one) . Its in hexadecimal
6.Save it all. Reboot to MacOS X , set the time properly and now boot back to Windows. You should notice the time should be alrighty
Fixing it in Linux (Thanks to Apocolipse)

Oh, and side note to mention, for linux users (who’s distro defaults to Local time not UTC, like ubuntu, for windows compatibility) you can also edit /etc/conf.d/clock CLOCK=”UTC”

Read the comments below. There are few suggestions (alternative methods) posted by Mac and apocolipse. Its a must read
The Reason why Time gets out of sync
No its not because of your alarm clock , no not jet lag either. Its because OSX uses UTC (aka GMT +0) to store its time. When you set your time zone for instance to +8 GMT (Singapore) , it stores the time with reference to UTC. When you boot to windows , the time that you’re actually seeing is UTC. But if Windows sets the time , it makes OSX all cranky. So the only way (well one of the ways) to fix it is in Windows. Another thing to note is that your BIOS clock will be in UTC and not in your local time 😛 (but dont worry about it , both of the oses will understand that your BIOS clock is UTC)
