Trying to install an unsigned application in OS X prompts a warning message telling users that the software may not be safe to install and use.
It works differently than the SmartScreen filter that Microsoft uses to prevent dodgy apps from being installed in Windows 8, but the intent is similar. Gatekeeper was introduced in OS X 10.8 as a way to reduce the risk of malicious software installation. This is contrary to a message Apple sent to developers in early August, which indicated that all apps would need to be re-signed to work properly with 10.9.5. However, developer Daniel Jalkut of IndieStack reports that most applications with v1 signatures continue to work properly. This had caused some consternation among developers who prefer or need to build applications in older versions of OS X or with older versions of Xcode, especially since Apple has not been especially clear on why the move to new signatures is necessary. Previously, Apple had said that all Mac apps would need to be signed with v2 signatures to work properly with the Gatekeeper security feature in OS X 10.9.5 and later versions. Apple recommends that developers build, sign, and test their apps on Macs running OS X 10.9 or OS X 10.10 Developer Preview 5 or later to make sure that the new signatures are working properly. Beginning on November 1, all OS X applications submitted to the Mac App Store will need to be signed with new v2 signatures. There's a larger, potentially disruptive change in 10.9.5 coming for developers.
The latter problems were fixed by updating from OpenSSL version 0.9.8y to 0.9.8za.
For businesses using OS X, the update fixes a problem that could keep system admins from "performing some administrative tasks successfully" on larger groups of Macs, and it also speeds up authentication "when roaming on 802.1x networks which use EAP-TLS."Īmong the security updates are fixes for Bluetooth, CoreGraphics generally and the Intel graphics driver specifically, and OS X's version of OpenSSL among many others. The new features include Safari 7.0.6, improved "reliability for VPN connections that use USB smart cards for authentication," and better reliability for connecting to file servers that use the SMB protocol. But I think Onyx will help more as it clears built up cache files and more.Further Reading Apple releases OS X 10.9.4 with wake-from-sleep and Wi-Fi fixesLike OS X 10.9.4, the update focuses on smaller problems that affect a subset of Macs. Your friend's idea of cleaning out files will only help to free up disk space - which could be part of the issue if your drive is really full. Post back results and any more information you have. IF your hard drive fails the SMART check that Onyx runs on startup you will need to open Disk Utility and run disk repair and permissions repair then run Onyx.ģ. Run the Automation mode and restart your mac. It is free and once installed it will run a check on your hard drive and then open up the interface.
It will do a lot of cleaning out of stuff you do not need and it is very safe. Be sure to pick the version that works with your version of OS X.
I suggest you download a utility called Onyx and run it. On the screen that opens up click on the storage button and tell us how large is your hard drive and how much of your hard drive is free.Ģ.
How full is your hard drive? Click on the apple icon in the upper left corner of your screen and select About this Mac. First if your computer is running slow a bit more information would help.ġ.
