Apple don’t want that to happen.

Not because they want to extract more money from hardware sales (Apple hardware is actually cheap for the quality you get anyway), not because they wouldn’t sell OS X as a product if they could.

It’s really simple: they did the math on the support costs of random third party hardware, and the numbers came up “nope”.

Apple actually did this long before OS X was a thing; for a short while you could actually get a licensed non-Apple MacOS computer.

But the support costs killed it.

To actually do this and make money, they’d have to sell OS X for a couple of thousand dollars, or maybe a subscription at about $50/month. That’s to pay for the three or four thousand developers and ten or so thousand support people they’d have to hire to deal with all the random crap hardware out there.

And it still wouldn’t meet their quality targets anyway.

So how can Microsoft do it?

They get the OEMs and hardware manufacturers to deal with most of it. Which they mostly do badly, but people have somehow become used to the resulting mess.

Making the OS itself free does mean that they don’t want people to install it on third party hardware because that would mean zero profits from the extra user (unless they use services such as iCloud in a premium fashion — more than just what’s given free).

I guess that makes the hackintoshing phenomenon an issue. Now, when the support for the last Intel based Mac ends hackintoshing will be a real issue (I mean, some explicitly limit themselves to High Sierra because of some NVidia GPUs that aren’t supported on newer versions at all…). But for now, if you have good, compatible hardware, you can reap the benefits just fine.

I am currently a hackintosher but intend to get an actual MacBook Pro (Intel based) soon. Wouldn’t have happened if I didn’t get a good hackintosh. So I’d say, don’t fight those who try it out like this and then migrate to actual Apple products, since that’s actually a profit vector. Only fight those that do it despite that.

The better question to ask is “How does Linux do it?”. You can find drivers for most of “the random crap hardware out there”… You can “google yourself” the support for most of the issues you’d run into, unlike Windows, etc. Support is a “thing” mostly for corporate users. Companies need someone to sue in case they’d somehow lose a penny because of hw/sw issues.

Using Windows would be much better than hackintoshing. Windows has its issues, it is not as reliable as macOS. However, Windows is much more flexible than macOS. It is much more programmer friendly than macOS. Most of the advantages of macOS will cease to exist once you take it out of the integration with Apple hardware.

You can, not so easily, run the OSX on a windows machine as you would run a second version of windows or Linux or any other OS. My current machine has around 4 different OS in 2 drives. The machine was originally assembled keeping in mind running it on OSX, endearingly known by the community as Hackintoshs. I did run an OSX version of Snow Leopard for a few months but didn’t have much use of it as I already own a MacBook Pro. A fun project but not without hastles.

Also, I did shift my 10+ year old MacBooks drive into the machine, before writing this reply, just for fun. Given the changes over time, the OSX failed to recognise half the peripherals which is solvable, but would need a lot of work.

You can. Such computers are called a “Hackintosh.” The procedure is totally unsupported, but I suppose it can save the user some money, when it works.

It’s not that it can’t. It’s a violation of the end-user license. If you’d like to give a try, just google out Hackintosh. I am not aware of any prosecution if you do. Definitely nothing like the infamous Microsoft initiated BSA raids on companies and individual users.

  • Updating to Catalina made my Mac worthless
    by /u/RookieParade (Mac) on December 1, 2022 at 4:15 am

    Just for clarity, i use a few different editing programs on my computer that require me to be on a not so current Mac OS. I finally updated my (late 2013) Mac to Catalina. My computer was working perfectly fine before the update and now it barely even works after the update. It's a little infuriating. Feels like a total planned obsolescence situation. Has anyone else had this happen or have a solution to this problem? Thanks in advance! submitted by /u/RookieParade [link] [comments]

  • Help with multi-output devices and changing volume.
    by /u/Egg-MacGuffin (Mac) on December 1, 2022 at 2:44 am

    My OS version is Mojave. tl;dr - Is there any app or method that allows me to use the volume keys to change the built-in output/system volume that I can hear through speakers or headphones, but NOT the volume on the Blackhole audio device that is being used for screen recording? Through the internet, I found out that in order to record system audio in a screen recording, you need something like Blackhole. I've been able to successfully set everything up (though I don't know what the point of an aggregate device is if you're not recording with a microphone, it doesn't seem to have any use to me and I can get by with just a multi-output device). The problem is that in order to record audio, I can't just point to the multi-output device in a program (programs don't even see it), I have to change my system's audio setting to use the multi-output device in the system settings. When you do this, you cannot change the volume with the keyboard keys. And if you go to sound settings or check the box to show the volume icon in the menu bar, you have to switch to the built-in audio, change the volume, and switch back, OR go to the midi settings and drag the volume slider of each left and right channel since the master option is grayed out for some reason. I found an app called MultiSoundChanger which allows me to change the system volume that I'm hearing in my headphones even while the multi-output device is selected in the system sound settings. BUT, this also immediately sets the Blackhole device's volume to the same as the built-in output volume, meaning that any recording is super quiet. I can set the Blackhole audio high and the built-in audio low so it doesn't explode my ear drums, but if I ever want to change it, It will mess up the recording in one way or another. Is there any app or method that allows me to use the volume keys to change the built-in output/system volume that I can hear through speakers or headphones, but NOT the volume on the Blackhole audio device that is being used for screen recording? submitted by /u/Egg-MacGuffin [link] [comments]

  • Are 1080p images always upscaled on 4K iMacs?
    by /u/ChamberKeeper (Mac) on December 1, 2022 at 2:02 am

    I was at apple store recently trying out the new 24" M1 iMacs and noticed something strange. If saved a 1920x1080p picture to it and opened the image in either quick look or preview it would strangely take up about 80% of its 4K screen. Why does this happen? A picture that size should take up closer to ~25% of 4K screen. No matter what I did I couldn't the computer to display the image accurately, I always got this weird upscaled version of the image.

    Now that my mac is hooked to a 38" widescreen monitor the performance is much worse. The cpu load goes crazy in more demanding apps, such as logic, ableton, zoom, OBS etc. Is this normal? Is it because of the mac warming up due to being closed inside my desk? If so, should I get a cooler to put underneath it or something?

  • Is there a way to transfer photo/video to Mac using ONLY Cable?
    by /u/RafaelSwi (Mac) on December 1, 2022 at 12:37 am

    I've recorded a really long video, and was trying to transfer it to my Mac. I Connect my iPhone to my Mac, and recognizes the iPhone. OK. I Open Finder to see if I'm able to see my video file, and nothing. Open the Photos app on my mac, and nothing. Open the "Image Capture" program, and still nothing. All photos/videos are appearing, except my last one. I realized that the video has still not been fully uploaded to the Cloud, for this reason, it's not appearing for me to transfer. The thing is, I want to use my cable. The video is REALLY big, I really don't want to wait to upload to the cloud, just for me to Download the same video again on my Mac. It seems like connecting my iPhone to my Mac using a cable is the equivalent do nothing, because if I cannot transfer a file directly, what is even the point. I don't want to use the dawn cloud service. Any external program that solve this? submitted by /u/RafaelSwi [link] [comments]

  • Did anyone go from an 8 GB M1 Mac to 16 GB because of performance issues?
    by /u/EveryLivingLine (Mac) on November 30, 2022 at 2:30 pm

    I bought into the “8 GB on M1 is enough!” parade and I’m paying for it. I don’t even do that intense of stuff, but using Lightroom (cloud), Photoshop and Spotify and Chrome absolutely CRIPPLE this computer. It’s kind of crazy. If I close everything but the one app out and I’m actively using it, I can work decently. But throw anything more into the mix and there’s stuttering, app freezing, Spotify sputtering out, etc. I’m wondering if it’s worth it to sell my 8 GB Mini and just get the 16 GB version? Even though going up to 16 GB is only a $200 upgrade when buying new, looks like I would only be able to sell the 8 GB Mini for something like $450 and 16 GB Minis go for $750 or so. So almost $300 to get out of this stuttering, slow Mac hellscape… submitted by /u/EveryLivingLine [link] [comments]

Windows Boot process

You can translate the content of this page by selecting a language in the select box.

What is involved in Windows Boot Process:

Windows_Booting_Procedure

    • Power is turned on.
    • The first process starting when you turn on your computer is BIOS i.e, Basic Input Output System. BIOS has two functions, to conduct POST and read MBR.
      1. POST – POST stands for Power On Self Test. POST checks all the hardware devices connected to a computer like RAM, hard disk etc and make sure that the system can run smoothly with those hardware devices. If the POST is a failure the system halts with a beep sound.
      2. Now BIOS checks the boot priority. We can set the boot priority as CD drive, hard disk or floppy drive
      3. MBR – The next duty of BIOS is to read the MBR. MBR stands for Master Boot Record and its the first sector on a hard disk. MBR
        contains the partition table and boot loader.
    • Functions of Boot loader
      Now BIOS has passed the control to boot loader and boot loader is a small program which loads kernel to computers memory. Actually there are two stages of boot loaders, stage 1 boot loader and stage 2 boot loader. MBR contains the stage 1 boot loader and stage 1 boot loader is a link to the stage 2 boot loader. The stage 2 boot loader resides in the boot partition and it loads the kernel to memory.
    • Boot files and functions
      There are three boot files in a Windows operating system and they are NTLDR, NTDETECT.COM and Boot.ini. The boot files are found in the active partition of hard disk and its normally C drive in a Windows machine.

      1. NTLDR – NTLDR stands for NT Loader and its the second stage bootloader. The path of NTLDR is C:\Windows\i386\NTLDR.
      2. Boot.ini – Boot.ini contains the configuration files of NTLDR. When the operating system is loaded we cannot pass any arguments to kernel, so those arguments are passed through boot.ini. You can edit boot.ini by opening through notepad. The path of Boot.ini is C:\boot.ini.
      3. NTDETECT.COM – This file detect hardware’s and passes information to NTLDR. Using the collected information the NTLDR creates a hardware key and this key is used to detect hardware’s. A new hardware key is generated after each reboot of the operating system and that’s why system asks to reboot after installation of a new hardware. The hardware keys created by NTLDR can be found in Windows registry at
        HKEY_LOCAL_MACHINE -> HARDWARES.
    • Kernel and its functions
      After executing the functions of boot files the control is passed to Kernel. ntoskrnal.exe is the kernel file in a Windows machine and its path is C:\Windows\system 32\ntoskrnal.exe. Kernel acts as a layer between software and hardware. The library file hal.dll (C;\Windows\system32\hal.dll) helps Kernel to interact with hardware’s. HAL stands for Hardware Abstraction Layer and this hal.dll file is
      machine specific. Now the drivers for hardware’s are loaded from the file C:\Windows\system32\config\system and the Kernel is loaded to primary memory.
  • Services and log in procedure
    When kernel is loaded in the primary memory services for each process is started and the registry entry for those services can be found at HKEY_LOCAL_MACHINE – System – Current control set – Services.
    Winlogon.exe (C:\Windows\system32\winlogon.exe) is the last service started during this process.
    Winlogon.exe starts the log in procedures of windows machine. It first calls the library file msgina.dll (C:\Windows\system32\msgina.dll). MSGINA stands for Microsoft Graphics Identification and Authentication and it provides the log in window. Now msginal.dll passes the control to LSA (Local Security Authority), it verifies the username and password from the SAM file. SAM (Security Accounts Manager) contains the information about all users created in a Windows operating system.
    Now the booting procedure is over and we have reached the desktop of Windows operating system.

Check how many CPU cores on Windows and on Linux

You can translate the content of this page by selecting a language in the select box.

How to check how many CPU cores I have on Windows & Linux?

What is a core in a CPU?
In summary, a core is a small CPU or processor built into a big CPU or CPU socket. It can independently perform or process all computational tasks. From this perspective, we can consider a core to be a smaller CPU or a smaller processor within a big processor.
Today, CPUs have been two and 18 cores, each of which can work on a different task. A core can work on one task, while another core works a different task, so the more cores a CPU has, the more efficient it is.

Open a command prompt (Windows) or Terminal (Linux) and type:

Football/Soccer World Cup 2022 Guide and Past World Cups History and Quiz illustrated

  • Windows: WMIC CPU Get /Format:List
    Capture_Check_CPU_Cores
  • Linux: cat /proc/cpuinfo | grep processor | wc -l
    For more details on Linux: ls /sys/devices/system/cpu/

What does 4 CPU cores mean?
A quad-core CPU has four processing cores in a single chip. It is similar to a dual-core CPU, but has four separate processors (rather than two), which can process instructions at the same time.
