Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Do you know your administrator or user login password ?
This happens if the Keychain database is corrupted. So we need to get rid of old keychain database and make a new one. First go to System Preferences select iCloud. Click Sign Out button there and sign out. If asked to delete or keep stuffs, select Keep. If you only see Delete, then click Delete or OK. It is OK, you can reconnect to iCloud later. This is very important step.
Once you did that, click on Finder icon on dock. In Finder, hold down Option key on your keyboard, click on Go menu at the top bar and select Library. In Library, open Keychain folder. You will see many files there in Keychain folder. Trash them all.
Then restart your Mac and this will force your Mac to setup a new Keychain folder. If that didn't work, then you have to boot your Mac to Safe Mode and then repeat the above steps. To boot into Safe Mode, turn off your Mac, turn it back on and immediately hold down Shift key for 20 seconds. This will boot into Safe Mode.
Please let me know if that didn't work, so we can continue troubleshooting. Remember, keychain mess is not easy to fix, so it will take some time and few efforts to get it sorted.
Note : This is not my final answer. I strive to provide Excellent service or 5 star service. If you feel you've received anything less or if you are not satisfied or if my solutions didn't work, please don't rate me bad or poor or ok. Instead, please let me know and I will try my best to help you until you are fully satisfied or the issue is resolved.
If you are already signed out from iCloud, then skip it. That could be the issue as you probably used Keychain before and your Mac is looking for keychain in iCloud. So please follow the steps below
Turn off your Mac, turn it back on and immediately hold down Shift key for 20 seconds. This will boot into Safe Mode. Then In Finder, hold down Option key on your keyboard, click on Go menu at the top bar and select Library. In Library, open Keychain folder. You will see many files there in Keychain folder. Trash them all.
Restart normally. This will force the Mac to create a new keychain database locally unless iCloud mess up it again. Let me know how it goes
Add a bookmark of this page oar add this page to your favorites, so you can get back to me after restart.
I want you to attempt to sign in to iCloud again. Then sign out and trash the files. But do these steps in Safe Mode. We need to force your mac to look into local Keychain instead of iCloud keychain.
How is it going Ed ?
Safe mode will be slow. It is for troubleshooting.
Yes, try to login to iCloud now. If asked to use Keychain by iCloud, don't use it.
Yes, do it
iCloud may ask you to use iCloud keychain. So don't use it. Then restart normally
Turn it off. Wait 2 minutes and turn it back on normally.
Is it still slow ?
It is not supposed to be this slow. I think we're not just dealing with simple keychain issue, but might be software corruption. So when it turns on, I want you to backup all your important files ASAP to an external hard drive
Let me know the results please
Let it load. Then backup your important files and we can do some troubleshooting to fix system files, memory etc
Internet won't work properly in safe mode. Only minimal functions will work in safe mode. But you should be able to backup all your important files in Safe Mode. Let mek now once you did that
If you don't have any important files on it, then you can format/erase it for Mac, so you can use it with your Mac.
Do you have any important files on it ?
If you don't have any important files on it, then you can format it for you Mac. Formatting will delete everything from it.
Connect the external drive to your Mac. Then go to Applications > Utilities folder and open Disk Utility. In Disk Utility, select your external hard drive in the left column.Under Erase tab, select Mac OS Journaled / Extended
Then click the Erasebutton and it will be formatted for Mac. Then you can copy your files to it
Oh ok. There are some methods to fix system files, but I don't want to troubleshoot without backing up your files.
You can connect the Mac to router via Ethernet cable and this will give you internet. Then download and install this application (use trial version) and it will allow you to write to PC formatted drives --> https://www.paragon-software.com/home/ntfs-mac/
Then backup your files. Or you can backup to DVD/CD
No problem. Take your time.
Resetting keychain should have affected the passwords saved in Safari. I want you to reset the PRAM and NVRAM of your Mac. It is a temporary memory and safe to reset it.
Shut down your Mac
Restart and immediately hold down Command-Option-P-R keys at the same time
Hold the keys down until the computer restarts and you hear the startup sound for two times.
Release the keys and let the Mac boot up.
We cleaned some temporary memory. How is the performance now ?
That indicates hard drive is busy with something. Probably slow reading and write times or it could be failing.
It is not supposed to take this much time. Slow issues indicates issues with system files, failing hard drive etc
The fact is, traditional hard drives are mechanical and may fail without any reasons - slow performance means it is dying. They don't have much life. Most of the new computers comes with SSD.
Even if the hard drive is not failing, it is definitely worth replacing it with an SSD and you will definitely see the performance boost.
Re checking hard disk, we can run Disk Utility and see what is returns. Before running this (it may make things worse on failing drives), make sure you backup all your files.
Turn off your Mac by holding down Power button for 10 seconds. Then turn it back on and immediately hold down Command and R keys at same time for 20 seconds and this will boot your Mac to the Mac OS X Utilities screen. From there, click Disk Utility. Select your hard disk at left column (Macintosh HD or hard disk name).Then click First Aid button and run it. Repair if asked.
This can't detect mechanical failure, but will tell us if there is any issue with system files.
Then don't run Disk Utility. It may make it non bootable.
In some rare cases, it could be the hard drive cable. If you are going to replace it, then you should consider upgrading to SSD. See this sample comparision --> http://pcbuildsonabudget.com/wp-content/uploads/2016/01/ssd-vs-hdd.jpg
