Apple Releases OS X 10.10.4 With 'Discoveryd' Process Removal

I upgraded 4 machines (2010mbp and 3 mac minis). My main mini has two (well, really only one) problem. When checking for trim in system report, noticed that the text layout is messed (as if the right margin of that window is way over to the left, pic attached). Not a big deal, mostly cosmetic. The second is that my start up screen is now black with a white Apple (aka iOS). My mbp is still white and gray, my other two minis I haven't checked as they are media computers and ya don't see the boot screen when accessing remotely.

Anyone else have these anomalies?

I believe the firmware updates were created only for mid 2011 and newer Macs....somehow I doubt that's because the old Macs are not vulnerable....The thunderstrike vulnerability depends on the system waking from sleep....so a way around it is to turn off your auto sleep setting and do shutdowns.

From Daring Fireball (http://daringfireball.net/) with regard to replacing DiscoveryD (radars are specific bugs):

"At WWDC, word on the street was that Apple closed over 300 radars with this move. Not dupes — 300 discrete radars."

Wow... To quote Luke Skywalker with regards to DiscoveryD..."What a piece of junk.." So glad someone (probably high up) swallowed their pride and rolled this back.

Go into your admin user and do the App Store check (sometimes that has helped me in the past). If no good there, look through the comments, some people have direct web links up for the updates and those should work. Good luck.

I was logged in, but when I clicked the Purchases tab, I had to log in again. After that the update was available.

Yes, I just stretched it out and it seemed to all fit like it used to. But yup had the exact same visual issue.

My boot screen (2011 MBP) gray screen with a larger loading bar.

XARA is a complex issue, there are several causes. However, looking at the security notes for 10.10.4, it looks like several causes have been addressed but it is hard to say that XARA is solved entirely. It is not likely but we'll have to wait for the XARA report authors to repeat their tests to let us know. It is likely some of the fixes may not fix it completely.

can you elaborate please? One thing which I thought would have been easy to fix was that no ACLs were enforced on keychain items deletion and any sandboxed app could delete a keychain items belonging to another app. this seemed like an obvious bug and one that should be easy to fix. but I don't see anything about this issue in the update notes. this would not have fixed the whole keychain exploit but it still should be done.

Interesting, I went to try that and low and behold, the display was normal. Maybe it just needed a couple more reboots (this am and after a crash). Still have the black screen with the white logo, kinda like it actually :)
 
Well, this is fun... App Store is stuck on "Checking for updates..." while eating 25% of my CPU.
 
Install went great here. Seems to fix the odd Apple TV Drop out i've been having. Also downloaded the full 5.6GB 10.10.4 from the Mac App Store at 850mbps. Took less than a minute. Recently had Fibre fitted. It's glorious :)
 
Does anyone know whether the WindowServer issue where it takes up 100%+ CPU when scrolling has been fixed?

everything like this for my two macbooks, too.

Tried several restarts, forcequitting, waiting etc...

I'm not sure I had the same situation as some of these others, but for me the App Store application simply showed nothing other than the in-window spinner. To clear this up, I quit App Store and issued the following command in a Terminal session:

open $TMPDIR../C/com.apple.appstore​

That opens the desired App Store cache folder in the Finder. I selected all the files in that open folder and deleted them, then emptied the trash (for good measure). Deleting the files in this folder can also be done directly from the Terminal but many users feel more in control if they can visually see what they're trashing first.

Launching App Store then immediately showed me the relevant new updates and my recently completed updates.

YMMV

850Mbit/s !!! Jesus where are you?
 
Anyone experiencing slower performance with 10.10.4? 10.10.3 was pretty smooth on my MBA, but Mission Control and some apps are choppy since running the combo update, especially on my external monitor.


I tried reinstalling the update, SMC reset, PRAM reset, Onyx cleanup and still slower--even after a couple days of use.
 
So it has now come to the day when a Mac OS X update is not featured on the homepage of Macrumors. Why do you deem it important enough to stick tutorials on how to synch music to your Apple Watch or, news on new international Emoji symbols, but a Mac OS X update, which is pretty critical for most of your readers, is not featured. I missed this article, when it was posted, because it was hidden away. I really wonder why I bother with this site anymore.

It actually fixed my external monitor issue that I had for the last 4 months. Pretty happy.

Everytime I turn my computer on it was putting it in low resolution and sometimes I had to turn monitor off and then on about 10x.

Wanted to take my words back. Nope it did not fix this issue :( . It came back next day.

Thank you for posting this! Some sort of warning should be provided on stories about enabling TRIM in 10.10.4+. I just got a Samsung 850 EVO (500GB) for my iMac and am planning to put it internal (right now it's in an external Firewire/USB enclosure so TRIM cannot be enabled). I *was* going to enable TRIM, but I won't now unless Samsung fixes the bug. Do we have any hope of that actually happening? Seems they've been called out publicly now so ...

I don't think it will impact you. I was also concerned. I installed a Crucial M550 and read the same arstechnica thread and related posts. The comments in the thread linked to https://blog.algolia.com/when-solid-state-drives-are-not-that-solid/
They are running Linux servers. Other posts referenced issues experienced with Linux and pointed to a blacklist in the Linux kernel that stops trim from being used on Samsung 8 series SSDs. The M550 at my firmware level was also listed there.

A comment by HungryBadger on arstechnica http://arstechnica.com/apple/2015/0...or-third-party-ssds/?comments=1&post=29311825 claimed only Linux used queued TRIM commands. I've also seen the statement on other posts that Windows and OS X both use sequential TRIM.

As best I can figure out the hypothesis is that NCQ support allows the SSD's controller to re-order commands and that was what was screwing Linux - but Windows specifically and OS X [as well - based on links I browsed] wait until reads and writes are satisfied before sending TRIM commands and thus avoid the problem.

Doesn't excuse Samsung though - they claim their drives support queued TRIM but the say Linux is an unsupported OS and Linux is the only one that uses queued TRIM ... catch 22 ?

Thanks for posting follow-up. After reading other posters more knowledgable on how OS X uses TRIM, I did proceed with enabling it after installing the Samsung 850 EVO in the iMac over the weekend. Of course, I'm still covering my bases via Time Machine backups to my server (and I may add an external hard drive as a second target as well).

There is another thread on macrumors more specific to trimforce. This post also summarises as "no queued TRIM in OS X hence no problem"

Updated, turned machine back on, horrendous wifi drop out for 15 minutes. Dropping every 30 seconds. Sadly don't think they've fixed it...
