Questions concerning the Macintosh Operating System (very technical)
I've recently learned all about how Windows based machines do various things such as memory management, processor management, disk scheduling algorithms, concurrent/parallel processing and performance evaluation/simulation.
I'm interested in learning more about the Macintosh OS handles these various aspects, in comparison to what I've learned about the Windows based machines. Could anyone enlighten me, or point me to a link that would do so?
Appreciated!!
In addition to the previous posts, I would add the following links:
See the ADC link Differences between OSX and BSD UNIX for some specifics on the diffs between OSX and BSD.
Darwin uses the Mach kernel .
I would also recommend the books "The Design and Implementation of the Free BSD System" by Marshall McKusick and George Neville-Neil and "Programming under Mach" by Boykin, Kirschen, Langerman and LoVerso for general background info on FreeBSD and Mach, respectively.
You may also find useful info at several Apple emailing lists devoted specifically to the Darwin kernel and Darwin development .
Good Luck!

Hi All, I have question about the iMac operating system. I have the last updated. The problem when I manage the place of the folder windows they are all mixing up. I mean they not on the place where I left them. how to set they stay on the same place? I know there are different possibilities to set.
I tried but it not helped for me. What I can do? How and where can set this they stay on their place?
Thanks.
laciOption 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Concerning the linux operating system on the ideapad u510
hi to everybody
i've bought a ideapad u510 with windows 8 and i would like to install Ubuntu wubi like some application on windows8, but i don't succeed.
please, how to do that.
please i prefer the answer in french in order to understand good procedure
thanksTry disabling secure boot in the BIOS. And see if wubi is able to install.. let us know if this works . Run wubi with admin previleges and make sure that wubi and the ubuntu image are in the same directory
Essayez de désactiver démarrage sécurisé dans le BIOS. Et voir si wubi est capable d'installer .. faites-nous savoir si cela fonctionne. Exécuter wubi avec previleges admin et assurez-vous que wubi et l'image ubuntu sont dans le même répertoire ( Used Google translate)
Cheers and regards,

Click on the menu at top left of your screen, choose About This Mac and, in the panel that appears, note the Version no. in the form 10.n.n. Then update your product list so we can see what version of OS X you're running on the Mac — see this tutorial:

What are the supported Macintosh Operating System versions for IBM SPSS Statistics 18,19 and 20?
Question
I would like to know what are the supported Macintosh Operating system versions for IBM SPSS Statistics versions 18, 19 and 20?
Answer
Please see the list below:
- IBM SPSS Statistics 18 and 19 releases are supported on Apple Macintosh OS 10.5 (Leopard) and 10.6 (Snow Leopard) with Intel processor.
- IBM SPSS Statistics 20 release is supported on Apple Macintosh OS 10.6 (Snow Leopard) and 10.7 (Lion) with Intel processor.
- The IBM SPSS Statistics versions 18 and 19 are not supported on Mac OS 10.7 (Lion).
THIS MEANS THAT TO USE LION ONE FIRST HAS TO UPGRADE TO SPSS STATISTICS 20.Whilst the 2012-02-15 edition of IBM's matrix does not mention Lion, a few users have noted that:
• 18.0 can be troublesome
• an updated version of 18.x should be better.

PASWStatistics_1 803_Mac_Patch.dmg and IBM SPSS Statistics 18.0.3.4 Hotfix Mac.zip are no longer available from the spss.com domain, and I could not find them in an IBM domain. If you download from unofficial sources, proceed with caution.

At a glance, you might find that 18.0.3.4 is compatible with Lion. -
The problem is with the new operating system and sending photo via email when used in my iPad.
From photo I selected 3 photos to send via email. I choose the upload key and choose to send by email. Typing text on the email is very slow. This is solved by saving the email as a draft and opening the email again from mail.
Can you amend he system to allow emails to be sent from photo as previously.Have you tried restarting or resetting your iPad?
Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after the iPad shuts down, then press the On/Off button until the Apple logo appears.
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds). Ignore the "Slide to power off" -
How do I get the old operating system and data put into the background and have the new computer be a new computer with me recognized as an authorized user?
Hi, I see I haven't had any responses but these problems haven't been fixed.
I still haven't been able to transfer purchases from my phone to my comp so consequently have stopped purchasing on my phone.
I bought a couple of albums recently via itunes on my comp, and tried to tranfer them to my phone via a playlist, but the sync often crashes. One album transferred except for one song, and the other hasn't at all. What happens is that when I autofill from a playlist it often hangs for ages on the first song and then I have to quit the application altogether as nothing happens for ages. Basically, the whole Itunes software freezes.
After this I find it hasn't transferred any songs, but they do appear greyed out on my phone, which means it has transferred some basic data such as the titles, but not the song itself. When I try to repeat the process to complete the transfer Itunes tells me that it can't transfer because the songs are already on the phone, but they are not!! I can't click or remove on the greyed out items, so now I have a couple of almost full albums on my computer that I can't tranfer or install on my phone, and a whole bunch of greyed out songs on my phone that I can't play or remove!
The rest of the problems as above still stand. I downloaded the latest itunes OS updates but nothing's changed. I haven't done the very latest iphone update yet though because it says you need to make sure your stuff is backed up, and I don't want to lose the purchases I made on the phone that I can't transfer to my comp. I'm planning on uninstalling itunes completely and reinstalling but I have little faith that this will fix the issue.
Can someone please help at all?? I'm so sick of this! -
The program vectorworks 2008 (not 2009) does not work with the new operating system Mavericks, which is a disaster because it forces us to change the program, and is very expensive. Apple should fix this problem
Why should Apple fix the problem? Maybe you should consider NOT upgrading if an expensive piece of (obsolete) software you're running won't work with it...

I found the operating system very confusing and hard to use. No tutorial. Manual and online help were outdated. Tool bars, programs and documents randomly appeared and disappeared. Programs I installed completely disappeared. Anyone else experience this?
No need to apologize, Jim. I think your rant was justified. For years people have been telling me how easy the Mac was to use. Imagine my frustration when I finally learned from friends and users that it takes weeks or months to make the transition from Windows to Mac.
Still, I agree that I acted to too hastily when I returned my mini-mac to the store only three days after I bought it.
I'm going to try again, this time with an iMac. This time I'll keep it. Since this thread is for the mini-Mac only, I'll probably be starting a new one for the iMac.
Why did I decide to try again? Well, I do like the faster speed and compact hardware of the Macs. I also like the fact that I can install Windows and use that for my programs until I transition completely to Mac, IF I make the complete transition.
Thank you all for your suggestions and advice. I have paid attention to what you said.

The Welcome to the X1 Operating System opening screen question
I got a new X1 box today and went to install it and the screen seems to be stuck at the "Welcome to the X1 Operating System" screen. How long should this screen be on for before it advances in the installation process? My box also says boot and that is not changing as well. What should the box say?
Yes, the new box is hooked up in the exact same place where the old one was. Trust me, I have unplugged it many times. I have a technician coming out tomorrow.

I'm a retired IT professional desiring to assist a friend who owns a small business who recently experienced very malicious attacks on her computers from unknown parties operating anonymously on the Internet. Because
of her lack of preparation for such events, her future ability to continue to conduct her business was seriously threatened. The incident revealed, to my friend, the need to be prepared to deal with spontaneously occurring problems that create suspicious conditions
that arise with modern computer software before they can be analyzed in a sufficiently comprehensive manner to have an opinion regarding the appropriate course of action for obtaining a permanent remedy. In that, the ability to quickly react on the basis of
only suspicion is the goal.
I want to recommend an approach that involves maintaining an offline image of an operational system that is capable of running any of her computers. This image needs to include all of the software required to run
her business. In that, it is not limited to the operating system. This single image could then be used to restore any computer to a known reliable state should the need arise. This technique will also insure that each computer has sufficiently similar capability
to allow them to substitute for each other. Insofar as image restoration is itself an operation susceptible to causing unacceptable business delay I'm also recommending that each of the identical computers (i.e., from a hardware perspective) operate in a multi-boot
environment where a virtually offline backup can be instantiated via a simple reboot (i.e., an operation that all users of the Windows operating systems turn to when strange behavior is first observed). My intention is to limit the cloned system (i.e., partition
or C: drive) to the operational software. The business data along with storage for temporary data will be isolated on other partitions (i.e, mounted with other drive letters) accessible by each instance of the software eligible for multi-boot operation.
This kind of operation is something that I know how to setup on older versions of the Windows operating system. However, Microsoft has now dropped support for all of those operating systems and my much more limited
experience with the currently supported operating systems reveals that changes to the boot process will necessitate making changes to the specific preparations needed to build such an environment.
Before recommending that my friend replace all of her computers with new ones, that includes paying for new operating system (i.e., Windows) licenses, I need some assurance that the new operating systems are as
good as the old ones in this respect. These need to be relatively inexpensive desktop computers and we're only talking about a few of them. Let's say fewer than half a dozen. My friend is a sole proprietor and even though her business has become completely
dependent on what was once called personal computers she must operate on a fairly tight budget. This especially includes the budget for technology.
The articles I've been able to find on the Microsoft support websites seem to treat multi-boot as a situation where someone is running different versions of possibly difference operating systems whereas my need
to produce a single image that will both run on multiple computers as well as multiple partitions on the same computer. I'd appreciate finding some technical advice that applies to building such a system using a supported version of Windows.I tried the image creation/restoration described by Jared. I don't think it makes much sense to rely on an operational system to do such a restoration therefore I opted for method 3 which involves using a "System Repair Disk". My first
reaction is what a crude tool. The image creation process had no trouble putting the image on a simple network share. However, it appeared as though the restoration couldn't even connect with the device. I then copied the files to a USB drive.
In this case the repair disk said it couldn't find the files even though they were there. It offered no mechanism to even look and see what was there. It appears as though it will only find the image if it is located in a folder by the certain
name used on creation and it is in root directory. Not very handy.
As ugly as all that was when we finally come to the point of making the restore it looks like the only option is to restore the entire disk, which in my case would mean also restoring both the windows partition and the recovery partition. This just
isn't what I want to do. It is also something I wouldn't even consider doing unless it was the only possible way to recover from a failed hard drive.
In summary, unless I've completely failed to notice how it works that just isn't going to work.
I hope there is something better than this. What about WinPE and ImageX?
Absent anything useful from Microsoft it will be necessary to try using other software. Time to try Acronis! I guess. -
Hello,
There are an option that let us on choosing an browser in that will be open the Adobe Account from app-desktop Creative Cloud in the windows operating system?
...in the case this option not exist...
Please add an option (maybe in next update schedule) that will let us to choose a different browser not the default.
Adobe Cloud ,Behance also Prosite are very weak implemented on the Internet Explorer.
All the best,
CristianHi Jeff,
Thank you for the attention given! I know this ... CCloud,Behance,Prosite go very well with Chrome;Firefox browsers(I use also on this browsers).
In case that will set Chrome or Firefox as the default browser I'll lose modern (metro) Internet Explorer... I don't want to loose this browser because is using on different stuff...a taste option.
I try question more like an suggestion to Adobe (maybe a future thinking option) but my English writes are weak ..
All the beast,
Cristian -
Why does the new operating system not delete the moved files from their original locations - it seems like an enormous waste of space, time and effort to clean up every file once you've moved it - also, when transferring large amounts of files it becomes a very large problem remembering which files were transferred and which not.
You're going to need to be more specific, as I'm not quite sure I understand what you're talking about.
If you're referring to copying from an external hard drive or flash drive, and you want to actually move files rather than copy them, you can hold down the option key to force it to do a "move" rather than a "copy." This is not new behavior, though... the Mac OS has worked this way as long as I can recall (and I've been using it since 1984).
If you're having a problem with trying to move files from one place to another on a single drive causing them to be copied instead, that is likely because of some permissions issue preventing you from actually being able to move them. -
I just installed the Lion operating system, basically to upgrade my iPhone. I didn't realize that my Microsoft Office 2004 application would no longer work. I have been using Word for my writing and I receive most of my emails with Word attachments. I have been using Apple products for years, always touting their reliability and customer service. I am not a techie, I just want to be able to do what I do on the computer and Apple always fulfilled my needs. Now I am told because of some operating system gobbledygook, I have to go out and purchase new software to use Word. This is despicable. I see no particular benefit to using Lion, but I do see a lot of detriments. Apple now seems to have turned into Microsoft, making software obsolete so they can make more money and to **** with the customer. You can be sure that my next computer will be a PC. I have completely lost confidence in Apple.
I seem to never tire of saying this. It was for Apple when they first announced 10.7 to disclose this. Yes, it was widely reported -- or rather, rumored -- but not by Apple. And many people who have gotten caught by this assumed that Apple itself would have told them beforehand about the loss of this very important feature which they had come to rely on. As far as I know, not even in fine print, does this appear anywhere on the Lion announcement or any of its links.
I am not saying Apple had to continue Rosetta in Lion, or forever, just that if it was going to be dropped, it should have been made known.
As relative "insiders" we should not forget that many people don't have the time, habit or interest to do this kind of research. I think it is a breach of trust that Apple has never directly made this announcement or given people the opportunity to decide beforehand if giving up their PPC apps for a new OS is a worthwhile tradeoff. -
Good afternoon ladies and gentlemen!
My question concerns the impossibility to open RAW-files directly from the program Adobe Bridge. At the moment when you open a RAW-file from Adobe Bridge by double-clicking, RAW-file is opened only in Photoshop. In the settings Adobe Bridge - in "open RAW-files by double-clicking in Adobe Camera Raw» box is checked. When you try any changes in the settings Adobe Bridge system displays a message:
Bridge's parent application is not active. Bridge requires that a qualifying product has been launched at least once to enable this feature.
The entire line of Adobe products on my computer updated to the latest updates. Previously, a family of products Adobe Photoshop on your computer is not set. Computer - PC, Windows 7 Enterprises.<moved from Adobe Creative Cloud to Bridge General Discussion>
