So you have to ask your ISP provider the DNS info and put it into Network Preferences.Īnother point is when you use Automatic: it helps to raise the port you are using to connect as #1 in the list (OS X scans the ports in sequence respecting the order you has indicated. Internet access will be erratic (Server not found, lost connection, etc etc) if your ISP do not provide DNS info automatically (hence validating the Optional DNS field). That is why on the Network Preferences the DNS filed is marked (Optional). Without DNS info some application will work (those who resolve IP by themselves) some wont. After that OS X will also probably loose time on Resync time (if you use a time server on the net).
DISKWARRIOR 5 NEVER LOADS OR BOOTS FULL
Be advised that that may be a race against the clock and you shouldn’t expect to achieve full extraction.This is a problem with missing DNS (Domain Name Server) information. If you don’t have a full backup from which to restore, you can * try* to boot into Target Disk Mode and use your second computer to copy (your most important files FIRST!) to a known-good drive. There’s nothing else that can be done about a corrupt filesystem. If DiskWarrior fails, you will need to erase and restore your data. (Even better would be opening the iMac and physically removing the HDD, but that requires a special tool to remove the display and an external HDD enclosure.)
DISKWARRIOR 5 NEVER LOADS OR BOOTS CODE
This is in case the root cause is a hardware failure on your iMac you want to minimize how much code is run on it when you’re working with a live mounted volume. If you have access to a second computer and the appropriate cable to connect the two, I strongly recommend performing your DiskWarrior repair from the second computer via Target Disk Mode (reboot the iMac with the T key). Note that, depending on the nature of the corruption, there is no guarantee that it will be able to fully repair your drive, but I’ve had several drives over the years that were saved by DiskWarrior when fsck / Disk Utility could not. Since fsck has failed but you’re booting off an HFS volume and not an APFS volume, DiskWarrior may be able to help you. Only then can we determine if there is a deeper issue that caused the corruption in the first place (e.g., a hardware failure in your DRAM). That may not be the ultimate root cause of all this, but you won’t get any further in your debugging until you can repair your drive.
Can the Apple Stack Exchange Community help me better? I'd also like to note that I have seen these websites:īut nothing has worked. I'd like to note that now, a few weeks after the initial issue the iMac only makes it quarter way through the boot before turning off. Are there any other ways anybody knows hot to fix this? I'm also aware that this could be a hard drive issue, however, I'd like to exhaust all other options before I consider that. I'm aware there may be ways to fix this by reinstalling MacOS. I repeated this over and over but it didn't say anything different, just that the drive couldn't be verified completely. No change.īooted into Verbose Mode - everything went smoothly until it got to checking the Catalog File, where it stopped, before spewing an error message and shutting down after 3 seconds.īooted into Single Boot Mode by holding Cmd + S on startup and typing fsck -fy. Reset NVRAM multiple times by pressing Option + Cmd + P + R - no change. Performed Apple Diagnostics (on my iMac known as Apple Hardware Test) by holding D on startup. Recovery Mode - I attempted to boot into Recovery Mode by holding Cmd + R and succeeded, but when I attempted to perform first-aid on the drive, I got this:īooting into a different drive - I only have the recovery drive separate, so same result as (2). Unfortunately it simply doesn't get to Safe Mode, the iMac turns off half way. Safe Mode - I attempted to boot into Safe Mode by holding shift when I turned the computer on.
Here is what I have tried, and the various results for each: loading bar gets halfway - then simply turn off and die. It would get halfway through a very slow boot up - i.e. From there, the iMac simply refused to start up.
I waited for about 5 minutes then force shut down the iMac using the Power button. Ok - first things first, apologies for a long post - I have lots of details about this issue.Īs far as I can remember, about a couple of weeks ago I was working on my iMac (Late 2010, I believe running High Sierra) and it got stuck and froze (the spinning rainbow wheel of doom).
