Problems after update to El Capitan

1. When MacBook going to sleep seems that it eject all external drivers. I have external HDD connected via USB and when OS wake up from sleep i always have few message that my device was eject uncorrectly. It's killing my HDD...

I think you mean drives, not drivers. And yes, this is a persistent trouble with Energy Saver and third party peripherals ever since USB was introduced. Alas different devices have had different firmware requirements to speak the Energy Saver code, and need to keep up to date with the operating system if they are firmware specific. Some use a better firmware than others that doesn't need updating. Energy Saver does have an uncheck box for put hard drives to sleep. That helps for some hard drives but not all. My best advice, if you must use energy Saver, to manually dismount all external drives before letting your machine go to sleep. Or use Screen Saver instead of Energy Saver.

2. Sometimes when i wait my MacBook wake up from sleeping it just making auto reboot after unknown crash. I reported 100x times about it via modal window.

This may be related to #1. See if following my advice for #1 fixes number 2.

3. Finder freezing and Force Quit is not helping. Relaunch Finder is not help too. After few minutes all other apps freezing too.

Does this happen with no third party peripherals or drivers in use?

Is your data backed up?

Have you run Etrecheck to determine if there is any out of date software or drivers that might need updating?

I might add Epson has not updated their printer drivers on http://www.apple.com/support/downloads/ since El Capitan's release. Thus it may be premature for those with anything right now but Brother printers to upgrade to El Capitan. You'll see why on my FAQ*:

* Links to my pages may give me compensation.

After updating to el capitan, ran ok at first. Then after a reboot, it freezes my macbook pro at the logo screen, everytime ⚠.

I've seen many posts alluding to this problem...with adhoc fixes like removing *.kext files , touching them, etc.

This latest OSX *****, compared to yosemite. why release this sucky version ?

And yet more people complained here about Yosemite than El Capitan. I find that odd. Try running an etrecheck report and posting it for analysis. Doing so in your own thread would be advisable so as not to hijack this Posters thread and confuse things.

Ok. Moved my thread to the appropriate thread. See this thread by afventer

El Capitan hangs at reboot

I saw your post because I am looking for a solution to my SCX-4200 printer as well.

After some research and testing with my El Caption OSX, I managed to make the SCX-4200 working.

El Caption OSX no longer support SCX-4200 natively, so need to use Samsung software, and the closest one I can find is SCX-4600 and when checking the software, I noticed is it using the universal TWIN SCAN engine, so I am comfortable it will work.

I install the Samsung SCX-4600 scan software without the ICA driver, printer work as normally via OSX, and I need to start the Samsung scan/fax utility to perform scanning. Not the same way I just the scanner before, but it works.

Hope this help.

Hi KLWONG,

Could you please post the link you downloaded the software? The one I downloaded from samsung doesn't seem to work.

Cheers

Thanks

Hi,

I found this link but I dont recognise it is the same one I used, it is the first ZIP scan driver file. Let me know if it is not working and I can put my ZIP file onto a dropbox link for you to download.

Thanks for your reply. It still is not working. Even the printer failed and shows error message as "Filter Failed".

Please share the ZIP file in dropbox if possible - that would be great.

Thanks again

Sorry for my late reply. I just send you the link to download the zip file. Let me know when complete. Thank you

Hi

I have the same problem.

Would it be possible to send me the link as well?

It would help a LOT!!!!!

Sorry I forgot where I download it, so I dont have the link. El Caption will recognise the printer without the software, it is only the SCAN function that need to install a seperate software from the zip file. If you got an error with the printer, I suspect it could be a different problem.

HI,

Thanks for sharing the zip file. My printer works now it not the scanner! It still shows the same error message!!

cheers
