Use createinstallmedia on the OLD installer (the one with the expired certificate) to create your bootable USB drive. Once created, open the USB drive and move the installer app 'Install macOS Sierra' from the USB drive into the trash and empty trash. Although it will seem like the USB drive is now blank, it isn't.

Error dmg aborting because no mount point found will

The Mac OS X series is one of the best line up series of the operating systems. The tenth edition in the series is the Mac OS X Yosemite. The biggest and most advantageous part of the Mac OS X series is that the versatility of the operating systems in making the user is more comfortable in using the system is high compared to that of the other range of OS series. Erase the drive you want to do the clean install, install El Capitan to the wiped drive, create your login account, boot from the new account on the freshly installed drive, then run the Sierra InstallOS.dmg (downloaded in Step 4) and InstallOS.pkg (Step 5) to create the 'Install macOS Sierra' app in the Applications folder. Launch the 'Install. After installing 7-Zip, you can simply double-click a DMG file to open it and browse its contents. If you’d like to extract the files from the DMG so they’re easier to work with, right-click the DMG file, point to the “7-Zip” menu, and then choose one of the extraction options. 2011-10-10 13:30:58.450 hdiutil438:2603 DIHelperProxy threadRunRunLoop aborting post-action runloop because retain count is good. 2011-10-10 13:30:58.450 hdiutil438:2603 DIHelperProxy threadRunRunLoop done with post-action runloop.

Two days ago I corrupted my file system during a failed resume from standby on Fedora 19. This feature has never quite worked correctly and randomly makes the kernel panic. Usually, I hard reboot my laptop and everything is fine but that time, something went wrong and when it came back up:

In this case /dev/sda2 is my root partition and since it was mounted even in maintenance mode, attempting to run fsck on it would output:

Which makes sense as common knowledge tells us that running fsck on a mounted file system will most likely do more damage to it.

The best option

Your best option is simply to boot into another Linux, be it on a different partition, a USB drive or a CD and run fsck Vocal chop vst free. manually on the faulty partition, which can easily be unmounted if necessary because no OS is using it. Easy. Normally yes, but my stupid Macbook Pro 2008 cannot boot though USB into anything else other than Mac OS X, my cd drive has been dead for years and recently, I got rid of my OS X partition. To make things more complicated, I’m in Thailand at the moment and obviously not able to take apart my computer to grab the hard drive and stick into a working system.

The other option (if you cannot boot into another Linux)

In order to assess the damage, I ran fsck in dry-run mode and piped the output to more to make reading more practical:

From there, I could ensure that no critical files had been damaged and while keeping in mind that it’s always a gamble to use a corrupted file system, I proceeded to boot into the system to make some backups. That out of the way, I did some research on the web on how to fix a root file system that I had to boot into and sadly, not many things turned up for its not an ideal solution. Forcing the system to do it a boot time by creating a file named forcefsck and writing y in it (echo y > /forcefsck) at root no longer works and adding fsck.mode=force on the kernel command line did not fix the problem as fsck will not fix errors on its own without authorization, ie: someone to enter yes on the keyboard. Tried a few other tricks but none worked. I had no choice but keep my fingers crossed and use the system as is.

A few days later, I decided to get back to the issue and while researching alternative solutions, I read that it was possible to fix errors on a read-only file system, which it turns out can also be used to boot into. Auto tune voice changer for singing apk. And it worked, so for posterity here is the technique:

Put your root partition into read-only mode by modifying the faulty partition’s line on /etc/fstab (but remember your old settings):
Note: If you’re already in maintenance mode at this point, you may be able to remount your file system in read only mode by running “mount -o remount,ro /” and skipping the reboot (thanks Jay).
Reboot
Switch to runlevel 1 just to minimize the amount of interfering processes (skip this step if you are running the session over SSH [thanks Josh]):
Fix your file system (replace /dev/sda2 with your partition’s device), which should now work because the root partition is in read only:
Reboot
Make your root file system readable/writable:
Restore your /etc/fstab to its original state.
Reboot

Build your own football stadium game. Voilà, your system is safe to use again. Hopefully this will have gotten you out of a sticky situation like it did for me. If errors keep coming up, it’s probably a sign that your hard-drive is failing and before you loose it completely, you should mirror your data to a new one.
