Apple Seeds Fourth OS X 10.11.2 El Capitan Beta to Developers and Public Beta Testers

by

Apple today seeded the fourth beta of an upcoming OS X 10.11.2 El Capitan update to developers and public beta testers, just one week after seeding the third beta and a full month after releasing OS X 10.11.1, the first OS X El Capitan update, to the public.

The fourth beta, build 15C47a, is available through the Software Update mechanism in the Mac App Store and can be downloaded through the Apple Developer Center. Public beta testers can download the beta through the Mac App Store.

We don't know exactly what improvements the 10.11.2 update will bring to OS X El Capitan, because the betas seem to be focused on under-the-hood upgrades with no apparent outward-facing changes. It’s likely to include bug fixes, security enhancements, and performance improvements to address problems that have popped up since the release of OS X 10.11.1.

Apple's release notes for OS X 10.11.2 have asked developers to focus on Networking, Graphics, Mail, Wi-Fi, Calendar, USB, Notes, Photos, and Spotlight.

@MacRumors

So now this is considered front page news again? Last week you moved it to the Mac Blog and now it's back once again. How is this even rumors?! This, while the rumor of a new 4" iPhone is moved OFF the main page to the iOS Blog.
Any OS X/iOS updates should be front page news by default imo. Macrumors is a website name. Not everything has to be a rumor.

Don't know why I got my hopes up.

SMB performance still sucks. 2.5 minutes to list a directory with 400 files in it? Really, Apple, that's the best you can do? Meanwhile, the older Macs and the PCs can list that directory in a matter of 2-3 seconds.

I've always tried to be platform agnostic and support whatever people want to work on at my workplace. I've defended the presence of Macs and quickly corrected people when they made false claims about how bad Macs were compared to PCs. But with Apple apparently having no more interest in supporting features that enterprise and business users need to get their work done, that's definitely coming to an end. Even I am having a hard time justifying keeping people on Macs at this point.

Sad, really. One key feature that used to work fine, hasn't worked for crud in the last few versions of the OS and is apparently not a high priority for Apple.

Well, hey, we got those new emojis though... :rolleyes:
Hello, I've noticed complaining about Apple on the internet has not improved your system performance, have you tried anything else?

Like disabling writing/reading .DS_Store on network shares
defaults write com.apple.desktopservices DSDontWriteNetworkStores true

Replacing Finder with Path Finder ('http://www.cocoatech.com/pathfinder/') or muCommander ('http://www.mucommander.com/')

Changing TCP Delayed ACK setting
In essence, several ACK responses may be combined together into a single response, reducing protocol overhead. However, in some circumstances, the technique can reduce application performance.
sudo sysctl -w net.inet.tcp.delayed_ack=0

Using SFTP/SSHFS instead.
