Used sudo to switch to 32 bit on MacPro Xeon with OS 10.7.5. How can I find out if it is using 32 or 64?

Used the command ' sudo setkernelbootarchitecture systemsetup - i386 "Terminal to switch to 32 bit on MacPro Xeon with OS 10.7.5. How will I know if it is now in 32 or 64 bit mode? I need to use 32 bit for some audio software I have, including Soundflower.

Also, I found 10.7.5 be shifted somehow. I don't want losing cumulative use audio and video software so can't go as a result of El Capitan. I have almost everything, including Java and Flash works well, but I really need to use 32 bits to record Zoom R24.

Sorry for the many questions but the Apple 10.6.8 to 10.7.5 transition point is a real mess.

Using Applications-> utilities-> activity monitor

Play with the activity-> display-> columns monitor to ensure that 'Gender' is displayed.

Make sure you view the process 'All' and not only of 'Your' process.

Then, look for kernel_task.  He should be among the 64 bits

The following text is from an El Capitan, which will very probably a little different from the Lion

What follows is a Snow Leopard system which is 32-bit by default.  You will notice that kernel_task 'Genre' snow leopard filed did nto say (64-bit).  If you have successfully changed your system from Lion to start the 32 - bit, then your kernel_task shouldn't say (64-bit).

    Hello

    Did you pay for Office (including Excel) in a packaging separated when you bought your computer?

    Office is not included with your purchase of computer for free.

    Most new computers come with a trial version of Office that lets 'x' number of days usuage.

    After this test times out, you will have to buy Office.

    And the product key on the computer case or laptop for the operating system, not for the desktop Suite.

    Here is the link for the Microsoft Store to Office products:

  • How can I find out which devices are using my subscription to plan photography creative cloud

    Yesterday I installed the rest of creative photography cloud on a 12 month pre-paid license on my desk.

    Photoshop installed ok but Lightroom installed as a 30 day trial and I spent nearly 2 hours to discuss for support before it was settled.

    Today, I just installed my 2nd installation on my laptop (because I think that I am allowed to) and both applications are reporting that I have already installed programs twice and I need to remove an instance before using the programs.

    I uninstalled the software from my laptop that I don't want to spoil my main office facility.

    Where can I find information of my installations of 1st and 2nd?

    Can I install the software on my desktop and laptops?

    Why facilities say they are already on 2 devices?

    Why the service account does not show these details?

    Why are they not more clear installation instructions?

    I don't know where you can find the installed or connected devices listed.

    You can install cc on an unlimited number of computers, but you are limited to two connections at the same time.  and you must be connected to use your programs of cc.

    When signing a 3d device, will give you the option of signature on the other two.  you will then know the only device to which you are connected.

    Open another application of office cc on another device and identify yourself and you will know 2 devices to which you are connected.

    If someone else uses your adobe id and password, you can see what appear to be anomalies.

  • Pav dv6t-1300, #VC034AV prod: HD crashed, how can I find out if the OS is 32 or 64 bit?

    Hello. My hard drive died last night and I ordered a replacement. I tried to order from sites of HP recovery disks, but he says it's not service this model more. So I looked online, found a place with the disks, but wondered if the OS is windows 7 32 or 64-bit.

    I spent almost the last hour looking for this info and online on any computer I can still access the original. This info was not listed in the BIOS or when I hit f2. I knew that the memory is 4096 MB of ram, if it's relevant somehow.

    Thanks in advance!

    If you go to the section of the user's Guides of the Technical Support for your system page, then click on the HP Pavilion dv6 Entertainment PC - Maintenance and Service of Guide , you will see on the page on page 1-2 that your system supports up to 8 G memory RAM. 32-bit systems are supported up to 4 GB of RAM, so I think it's safe to say that you have a 64 bit system.

  • disk space issues: How can I find out which components of the operating system I use is more to free additional disk space?

    HI: I have problems with disk space; I went to Windows Help and read that if I go into Add/Remove programs who said I could remove programs or components of operating system I no longer use. I remove some programs that I don't use anymore, but I do not know what operating system components I should delete!  Little help would be greatly appreciated! Thank you!

    Before you remove the services I would remove all but the most recent backup and restore point.  Then make a disk for temporary files Cleanup Wizard.  You can make you smaller file page, if you do not use put into hibernation, you can save 4-8 space gigis.

  • How can I find out how many computers is using my own account?

    I used to share my account with my friend, but he decided to give up and break this agreement. So, I would like to know if there is a way to know if one computer (that's me) using my accont or if my friend is using again. Thank you.

    First of all, it wasn't according to the license... Licenses and terms of use | Adobe

    Second, Adobe doesn't follow it you YOU enter

    -https://accounts.adobe.com/ , then click on Plans & products top

    Third, you will know if you try and install & activate on another computer and the system tells you that you have already used your two activations allowed

    If you have given to your 'friend' your private information to activate the software, there is no way currently to someone fix your mistake... Once you have given to your private information, you have lost control of your purchase
