Mac OS 10.12.1 Safari 10.0.1 Develop Menu enabled Disable Cache checked  Safari's cache is full of garbage as pictured.  For the past few years "Disable Cache" has blocked all this nonsense, but since upgrading to Sierra it no longer works.   Any ideas why or solutions? I can lock the cache file as a solution, but not as an answer.   Thanks!

I'm disabling the cache from Safari developer menu, but each time I reboot my computer, the cache is re-enabled.  I'm looking for a permanent solution for disabling the cache.  Any ideas?

Stack Overflow's new image uploader does not work on Mac Safari Version 12.0.1 (12606.2.104.1.2). I cannot drag and drop nor select from a list. It works fine using Firefox, Chrome and Opera. This just started today 10/31/2018 when I notice that there is a new interface for the image upload using IMGUR.  Please look into this and fix for Safari if possible or revert back to the old interface.

Apple has introduced , also known as "rootless", with OS X 10.11, El Capitan. I understand this is a step for general protection against malware but as a developer I need write access to some of the files it locks away.  How do I disable this protection?

All of a sudden, Safari on my Mac has started misbehaving. I can't select the text in the address bar, and so I can't go to any new websites. When it redraws, it goes all weird:    I've tried deleting the cache, clearing all cookies, disabling all plugins and rebooting. These things didn't help. I've had to switch to Chrome for the time being. Can anyone suggest some other possible remedies?

Mac Mini (Mid-2011), 16GB SSD, 16GB RAM, El Capitan (v10.11.6)  The Mac ran fine until I upgraded to Sierra. The latest Mac OS conflicted with most of the specialized apps I use every day, So I immediately returned to El Capitan.  Activity monitor shows that two "Installer/Installer.app" items are always running and are they major users of all of my available memory. Consequently, all my others apps become unresponsive.  I run Disk Utility, and the Installer.app show up there as .dmg files; but I cannot erase, delete, or unmount them. None of my 3rd party app can remove the installers.  My Mac Mini, which should be running super-fast (as it used to), now runs dreadfully and disgustingly slow. I a truly upset with Apple for this kind of garbage. To get their help: $$$.

I have been having issues with Finder and the Dock ever since the upgrade to 10.10.1 (I can't be certain they weren't there in 10.10).   I am unable to drag items off of the Dock (to remove them). I also can't drag items from the download stack that I have beside my trash can in the dock. Dragging the item simply does nothing. If I drag it somewhere and release the mouse button, it just opens the app/file. And in Finder, I am only able to drag and move/copy 86 items. I can select more but when I drag them to a new folder or other location the most that will get moved is 86.  I have confirmed the issue with a friend but have several other friends for which everything is working fine.   I have a mid 2012 retina MBP and my friend has an older (2010 i think) non retina MBP. I have restarted several times and tried to find any sort of setting that might be turned off. Googling doesn't seem to turn up any information either. So I am mostly wondering if anyone else is having this issue and/or if it is an OSX bug or how to fix it.  Thanks.  Update  Running repair disk permissions from disk utility then restarting worked for a while. But then things went right back to not working again. Going to test some things to see what might be causing it to revert.  Update 2  It turns out that restarting does fix it temporarily and repair permissions has nothing to do with it. I am assuming I didn't notice this before because it is being caused by an application that was reopening (because I usually check off the "Reopen applications" option).  Update 3  For clarity, here are videos showing what the issue is.    In this video it is working as it should be (right after a restart): In this video it is not working:

I understand there was a uninstaller for Safari 6 beta (is that available anywhere?) but it seems no longer available in the Apple Dev Center, and I am on Safari 6 release version.  I need to remove this and revet back to 5.1.7.

Search results for this question contain nothing but arguments for and against. Please take those up in another forum. I want to know is there an option, extension or hack to disable private browsing mode in each of the following browsers?   Apple Safari v?+ (Private Browsing) Google Chrome v1+ (Incognito Mode) Internet Explorer v8+ (InPrivate Browsing) Mozilla Firefox v3.5+ (Private Browsing)   OS-agnostic solutions preferred.  Depending on the use-case, alternate tools like traffic monitoring, OpenDNS or NetNanny might be valid, but they are not relevant to this question.

I got the macOS Sierra update when it went into public beta, and I've been trying to use the automatic .  I've enabled the feature, however since September 7 no files have been uploaded. By this point, the bottom of my Finder windows say:     15.78 GB available on iCloud, uploading 156,106 items (543.2 MB of 543.2 MB)   However the files are never actually uploaded. I keep my screenshots folder on my desktop and I take a lot of screenshots, so I can see that September 7 was the last date any file was actually uploaded.  What should I do? Is there a way I can disable and re-enable the feature without risking loss of data? Are there any solutions to this problem? What should I try? So far I've tried rebooting, and tried software update to macOS 10.12.2 public beta.

I want to display from cache for a long time and I want a slightly different behavior on page render vs loading the page from cache.  Is there an easy way I can determine this with JavaScript?

On my new site all works fine so far, except that when I try to clear cache (e.g. class cache or table cache or just flush all caches) from the UI. I sometimes get an error about exhausted memory (64M on production, 128M on test site).  Are there any alternatives to clearing cache from the UI? Can I just delete all records from the database tables starting with "cache" and obtain the same result?

After upgrading to macOS Sierra, I'm getting the notification that "Your disk is almost full. Save space by optimizing storage.":    The options appear to be to store my files in iCloud, automatically delete files, or manually delete files:    My problem/irritation is that I have 80GB free of my 440GB volume.  The question: is there a way to silence this notification in a (semi-)permanent fashion, or to change the threshold it uses for the notification?

After upgrading to High Sierra, I'm getting this error message about 30-50 times a day:    Is there any way to find out what is causing this error?  Any ideas how to fix it?

Sometimes it's hard to search for older versions of macOS &amp; OS X  on the App Store.  This is an attempt to provide the canonical QA for this issue, as per the Meta QA -  I expect it to be modified over time to hopefully become a complete information resource.  How can I get any older version of a Mac OS to be able to run as a VM, or to reinstall on my Mac?

Our investigations have shown us that not all browsers respect the HTTP cache directives in a uniform manner.  For security reasons we do not want certain pages in our application to be cached, ever, by the web browser. This must work for at least the following browsers:   Internet Explorer 6+ Firefox 1.5+ Safari 3+ Opera 9+ Chrome   Our requirement came from a security test. After logging out from our website you could press the back button and view cached pages.

I've already installed macOS Sierra. But I've also performed a "general" cleaning and I suspect some files were gone. Now the whole system is slow, some things doesn't behave the way they used to. Is it possible to download again macOS Sierra from AppStore and simple reinstall it? I mean, install macOS Sierra over macOS Sierra that is already up and running (not so well...). Thanks a lot for your help.

I just reinstalled high Sierra after my Mac wouldn't restart. The moment it loads up I am presented with this screen. My login credentials don't work. Can someone explain to me what this screen is and what I'm supposed to input?
