Rights of the Instsllation on an iMac

How can I switch from 3.6 on an iMac when Firefox refuses to proceed with an installation for the reason that I don't have the necessary user rights (even if I am logged on as administrator)?

This has happened

Don't know how many times

  • Time Machine deleted messages on an external drive to the trash can on iMac are taking place on the hard drive?

    I am struggling with a computer, try to empty the trash with 1million 300,000 Time machine backup files. It runs for two days now and won't install. At this rate, I'll need a week before my computer becomes viable. I don't feel able to go to the Terminal to do the trick. Also at this point, I'm afraid to stop the process again... Backups on an external drive of pigs 400 GB on my drive hard imac... I have so little room to work right now. I deleted some 200,000 files already yet the storage on my imac HD has not moved. The files in the Recycle Bin of the external drive really live on my hd now until they will be deleted if all goes well before Christmas?

    I have a new computer to come next week so I'm wondering if I'll just reformat my entire hd in my imac to solve this problem... Any ideas?

    You do all this in the Finder?

    Time Machine has to delete the files from the user interface, normally "browsing Time Machine backup", navigate to the desired folder, and select the option "delete all backups of...» ». This is the approved way that should work.

    If you are manually dragging the items in the trash of in a Time Machine backup, it can choke. Time Machine stores data with many levels of access control permissions & Finder seems to have difficulties to remove to empty the trash. In fact, I think that the TM drive has limits to prevent normal users to change data on this disk.

    Personally, I think your safest option is to abandon the process, restart, erase and reformat the Time Machine drive. Who will lose all history backups but again in a clean condition seems to be better than trying to manually prune the Time Machine data. Time Machine removes old backups when it is full - so you shouldn't really need to intervene like this anyway.

    Wait and see if anyone has a better idea.

    P.S., each disk has its own "basket", so doing drag items should not fill your Mac startup disk. Maybe the operating system is out of memory, try to process all the files, exit other applications & see if that changes anything, you may have to wait just if you want to avoid to abandon the process.

  • Buy unlocked iPhone 7 right after the release date

    Friends good day! Let's say I want to buy an iPhone 7 right after the release date before apple officially begins selling the devices free SIM card. I'd be able to come simply to store and buy, for example, an AT & T phone to use with my operator? Because I know that they would be not selling sim free phones in the first two weeks. Or do I have to buy a plan as well and become a customer of AT & T? In other words, I need now a unlocked device, and can I get one without waiting for the start of the free features of SIM card sale. Thank you!

    If you buy any iPhone outright directly from Apple full paying, it is carrier unlocked.

  • What is the problem with my iMac mid-2011

    Hello

    Need help find out what is the problem with my iMac to mid-2011.

    Yesterday during a reboot it just never came to life.

    On turning the power on, I get the RINGTONE to start and that's it. The screen is totally black. Nothing behind tried with a torch.

    VRAM rearmament so far I tried repeatedly, unplug and plug, all kinds of combinations of keys in the carillon and nothing.

    Connected to an external monitor and shows nothing of too - no signal.

    Any way that I can know what is wrong with it before sending it to the service tech? I suspect bad graphics card but how do you ensure?

    From what you describe, it looks like a hardware issue that Apple will only be able to resolve, but not to despair immediately.

    Read it please get help with graphics issues on external displays connected to your Mac - Apple Support.

    I know that the title and subject are not suitable to your concern, but buried in this document is the following passage that contains three links describing the steps to follow.

    If you can not change the resolution of your screen because you see no image, restart your Mac in safe mode to reset the default display resolution.

    If booting safe mode doesn't resolve the problem, reset your Mac NVRAM and SMC to reset the video ports on your Mac to their default values.

    That first, then write again for additional suggestions if you are still having problems.

  • New tabs open to the right of the current page, not extreme right?

    I liked using the new tab button, which disappeared from the most recent version, I had to go back to 38 to find it and put it back on my toolbar. However, I was not able to set the way in which the new tab opens, next to the page that I am. Previously, if I clicked on the new tab button, a new tab would open at the far right of the tabs. I tried to fix it by going to about: config, changing the browser.tabs.insertrelatedaftercurrent to 'false' to 'true' as was the fix in 2013. Alas, it doesn't now and I want to change it back. In addition, the new tab icon/button is gone for good in the new versions?

    If your new tab button opens a tab in the middle of your tabs, it could be a feature of an extension related to tab. Some of them, such as Tab Mix Plus and Tab Utilities have so many parameters it can be a challenge to sort through all of them. You can check your extensions and check if they have an Options button to tweak their settings, on page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click Extensions. Then go through the list on the right side.

  • What is the problem with the graphics on the upper right of the browser. Why is this happening?

    It gets a lot worse that what can be seen in the image on screen shot (below). This does not happen with other browsers (Safari, for example). This also occurs on the right side of my toolbar.

    The above mentioned page doesn't have to download, so here is a description of what happens:

    Flashing of the grey squares on the side right of the browser (the scroll bar and the parts of the web page) and on the right end of the toolbar.

  • right pointing the orange arrow next to sent the message in the sent folder

    I sent an email to my son and myself as well. The message was sent, but it never happened in my Inbox. I always do and my message is well received.

    On this occasion, I never received the message. There is a right pointing the orange arrow next to the sent message in the sent folder. I assumed that it was sent, but I didn't get the message in my Inbox.

    The message was delivered to the e-mail address of my son?

    What is going on?

    Thank you

    Using googlemail? They do not seem to approve copies to self supporting without doubt that there is a copy in sent, though it is not as stated in the letter.

    You have an alternate email address of your choice to send it to?

    I think that all this has worked in the past. What could have changed recently?

  • Notification of Firefox at the bottom right of the screen freezes Windows 7

    It seems that recently, Firefox (and maybe pop up notifications) are freezing my computer Windows 7. I used Firefox for years without this problem. In recent weeks, I noticed that system freeze seems to happen when a Firefox pop-up notification appears at the bottom right of the screen (for example Firefox 38.0.5 is available...). The mouse will continue moving the cursor on the screen for a few seconds, then that freezes at. I get no response from the keyboard, even CTRL-ALT-DEL and start button / stop fail to restart the machine. I need to remove and replace the power cord.

    Hoping that Mozilla has solved the problem I updated today to 39.0 Firefox, but when a plugin of Firefox browser introduced a notification in the lower right corner of the system froze again. I don't have this problem of gel when Mozilla Thunderbird shows a notification in the bottom right of the screen (e.g. XXXXXX received 6 new messages).

  • [Solved] Active tab automatically scrolls to the right of the tab bar

    Firefox 34.0.5

    Using the option [don't load tabs until selected], when I click on a tab that needs to be loaded, the tab is automatically scrolls to the far right of the tab bar, as you can see in this screenshot.
    http://PUU.sh/eAhdx/296a80d319.PNG

    Is there a way I can disable this behavior?

    [Solved] There was a conflict with an extension that appears to have been resolved.

    Could you clarify - which is what you see:

    • The tab you are activating moves to the bottom of the tab bar to the right
    • The tab you are activating kept his place even in the sequence, but Firefox is scrolled to the left on the tab bar if you end up seeing more tabs to the left of the you active and few of them to the right

    (I didn't notice either of those myself, but I try to understand what is happening).
