Linux users who want to run Windows applications without switching operating systems have been able to do so for years with Wine, software that lets apps designed for Windows run on Unix-like systems.
There has been no robust equivalent allowing Mac applications to run on Linux, perhaps no surprise given that Windows is far and away the world's most widely used desktop operating system. A developer from Prague named Luboš Doležel is trying to change that with 'Darling,' an emulation layer for OS X.
In order to effectively figure out what games your Mac can run, you should: 1. Download Valley and perform this same test (we explain the entire process in detail here). That result will be your reference point. Look for the game you want to play from our Can my Mac Run it section. See real-time CPU, network, or disk status in the Dock. It’s easy to keep an eye on your system status without even looking at the Activity Monitor window—you can monitor your CPU, network, or disk usage as a live graph right in the Dock.
'The aim is to achieve binary compatible support for Darwin/OS X applications on Linux, plus provide useful tools that will aid especially in application installation,' Doležel's project page states. Darwin is Apple's open source operating system, which provides some of the backend technology in OS X and iOS. The name 'Darling' combines Darwin and Linux. Darling works by 'pars[ing] executable files for the Darwin kernel. load[ing] them into the memory. and execut[ing] them.'
But there is a ways to go. 'Darling needs to provide an ABI-compatible [application binary interface] set of libraries and frameworks as available on OS X. by either directly mapping functions to those available on Linux, wrapping native functions to bridge the ABI incompatibility, or providing a re-implementation on top of other native APIs,' the project page notes.
Doležel, who started Darling a year ago, described the project and its progress in an e-mail interview with Ars. Darling is in the early stages, able to run numerous console applications but not much else. 'These are indeed the easiest ones to get working, albeit 'easy' is not the right word to describe the amount of work required to achieve that,' Doležel said. 'Such applications include: Midnight Commander, Bash, VIM, or Apple's GCC [GNU Compiler Collection]. I know it doesn't sound all that great, but it proves that Darling provides a solid base for further work.'

Users must compile Darling from the source code and then 'use the 'dyld' command to run an OS X executable,' Doležel said. One roadblock is actually getting Mac .dmg and .pkg application files working on a Linux system. Because doing so isn't that straightforward, Doležel said, 'I've written a FUSE module that enables users to mount .dmg files under Linux directly and without root privileges. An installer for .pkg files is underway.'
Unix/Linux synergy
The fact that OS X is a Unix operating system provides advantages in the development process. 'This saved me a lot of work,' Doležel explained. 'Instead of implementing all the 'system' APIs, it was sufficient to create simple wrappers around the ones available on Linux. I had to check every function for ABI compatibility and then test whether my wrapper works, so it wasn't as easy as it may sound.'
Another lucky break not available to Wine developers is that Apple releases some of the low-level components of OS X as open source code, 'which helped a lot with the dynamic loader and Objective-C runtime support code,' Doležel noted.
But of course, the project is an extremely difficult one. Doležel isn't the first to try it, as Darling was initially based on a separate project called 'maloader.' Doležel said he heard from another group of people 'who started a similar project before but abandoned the idea due to lack of time.'
Doležel was actually a novice to OS X development when he started Darling, being more familiar with OS X from a user's perspective than a developer's perspective. Chief architect x7 mac download. 'I have personally looked for something like Darling before, before I realized I would have to start working on it myself,' he said.
Darling relies heavily on GNUstep, an open source implementation of Apple's Cocoa API. GNUstep provides several core frameworks to Darling, and 'the answer to 'can it run this GUI app?' heavily depends on GNUstep,' Doležel said. Doležel is the only developer of Darling, using up all his spare time on the project.

No reverse-engineering
Doležel isn't reverse-engineering Apple code, noting that it could be problematic in terms of licensing and also that 'disassembling Apple's frameworks wouldn't be helpful at all because Darling and the environment it's running in is layered differently than OS X.' https://cleverjazz431.weebly.com/blog/dji-assistant-mac-app.
https://cleverjazz431.weebly.com/blog/rss-generator-app-mac. The development process is a painstaking one, done one application at a time. Doležel explains:
To improve Darling, I first take or write an application I'd like to have running. If it is someone else's application, I first examine it with one of the tools that come with Darling to see what frameworks and APIs it requires. I look up the APIs that are missing in Apple's documentation; then I create stub functions for them and possibly for the rest of the framework, too. Ios simulator for mac without xcode. (Stub functions only print a warning when they are called but don't do any real work.)
The next step is to implement all the APIs according to the documentation and then see how the application reacts. Best photo editor for mac integrated photos. I also add trace statements into important functions to have an insight into what's happening. I believe this is very much like what Wine developers do.
When things go wrong, I have to use GDB [GNU Debugger] to debug the original application.
It is rather unfortunate that Apple's documentation is often so poorly written; sometimes I have to experiment to figure out what the function really does. Many OS X applications seem to contain complete pieces of example code from Apple's documentation, presumably because one would have to spend a lot of time getting to understand how the APIs interact. This is why I appreciate open source so much—when the documentation is sketchy, you can always look into the code.
Years of development are needed. Similar to Wine, 'Having a list of applications known to be working is probably the best way to go,' Doležel said.
Slack desktop app. Darling should work on all Linux distributions, he said, with the catch that 'many apps for OS X are 32-bit only, and installing 32-bit packages on a 64-bit Linux system could be tricky depending on your distribution. I personally use Gentoo Linux, so I'm gradually creating a Portage overlay that would compile Darling and all dependencies for both 32-bit and 64-bit applications.'
Doležel would like to bring Angry Birds, other games, and multimedia applications to Linux. Darling could potentially 'be used to run applications compiled for iOS,' he writes on the project site. This will also be a challenge. 'The intention is to support the ARM platform on the lowest levels (the dynamic loader and the Objective-C runtime),' he writes. 'Rewriting the frameworks used on iOS is a whole different story, though.'
You might be experiencing some performance issues with your Mac and you knew from your PC days about defragging computers. Well, you won’t find any command or utility to do that on Mac. The point is that the Mac File System is designed differently than Microsoft's, and it defragments files automatically. However, there are still some situations when you may need to defrag Macbook once in a few years.
In this article, we’ll tell you how to defrag a Mac, all advantages and pitfalls of doing this, and what alternatives to defragging are out there. Anxious to find out? Then let’s start!
Do you need to defragment a Mac?
First of all, let’s find out why we do a Mac disk defrag. To cut a long story short, defragmentation is aimed at boosting a computer’s performance by reorganizing the data on your drive. As a result, the related bits are grouped together and loading files and programs takes less time. Simply put, Mac defragment moves everything back in order and can greatly speed up a slow system.
However, despite the obvious advantage, a Mac running any version of OS X later than 10.2 generally doesn’t need to be defragmented. The reason for this is that OS X and macOS have their own built-in Apple Mac utilities that clean up fragmented files from the hard drive. Therefore, for most users it eliminates the need to perform a regular defrag. But there is an exception to every rule and in a few rare cases a defrag for Mac can make a difference.
When do Macs need to be defragged?
If your hard drive is more than 90 percent full, the macOS may have problems with automatic defragmentation routines. This situation is common for multimedia creators who produce plenty of large files in pro tools like Adobe Premiere, Final Cut or Photoshop.
Therefore, if you have hundreds or even thousands of large (1GB and larger) movies, audio files or creative documents, you should consider removing them to free up the storage. Another alternative is defragging a Mac.

Concerning the first option, there is a fast and safe way to remove unnecessary files from your Mac — a powerful app CleanMyMac X. It finds above 74 GB of junk on an average computer, including old and large files, app leftovers and system clutter. It helps to boost computer performance, so you probably won’t even need to defrag a Mac.
However, if you still wonder “How do I defrag my Mac?” read on. We’ve prepared all essential guidelines for you.
How to defragment a Mac
One of the simplest and most user-friendly methods of a Mac defrag is to use a trusted third-party defragmentation program. But before choosing and installing the app, make sure to back up your data. Should something go wrong, you’ll be able to easily restore all necessary files. For this purpose, you can use Time Machine, iCloud, Dropbox or any other external storage at hand.

When choosing the defragmentation app, pay a special attention to the compatibility requirements. Macs running operating systems older than OS X 10.2 are not compatible with the latest modern defragmentation software, so finding a relevant tool is challenging.
Once you’ve installed the program of your choice, open the utility and follow the instructions of a disk defragmenter for Mac. Give the process plenty of time to complete and don’t move your computer anywhere until the defragmentation is finished. Usually, you’ll need to restart your Mac as well.
Will defragmentation harm my HDD?
You may not worry: OS X defrag will not harm your HDD. As you already know, disk defragmentation can greatly speed up the traditional hard drive. It’s because HDD fragments all the data and stores it in multiple locations. And it may take quite a time to read the file with its pieces situated in different places. The procedure of arranging the data is not harmful for your HDD and is aimed at boosting the computer’s performance. And while it is not advisable to turn to such extreme measures, defragmenting a hard drive disk is a safe procedure if, of course, performed accurately.
Why you should never defrag Mac’s SSD
The process described above is applied only to the hard drives. If you have a newer Mac that comes with SSD (solid state drive), you should never defrag its data. SSDs operate in a different way to a traditional HDD and already have a built-in automatic maintenance process. Therefore, it is not necessary to defrag a solid state drive to boost a Mac’s performance.
Furthermore, all defragmentation attempts can even hurt your SSD. Flash memory used by a solid state drive has a finite lifespan because of the limited write and read cycles. And disk defragmentation is a process of reading the data from one place and writing it to another. So if you defrag SSD, you will perform thousands of write operations each time on the drive. It can speed up the degradation of a solid state drive and lead to its wear and tear. And that’s not what you need.
What are alternatives to defragment a Mac?
If your Mac is running slowly, you don’t necessarily need to defrag Mac hard drive. Sometimes it’s not your HDD that’s having problems. Therefore, try some alternative methods that may help you speed up the system without disk defrag on Mac.
Repairing Disk Permissions
“Try repairing your disk permissions” is a standard Mac troubleshooting tip. Permissions are file settings that affect the ability to read, write and execute the file. And if they are no longer set correctly, software that uses the file may not work right.

In OS X Yosemite or earlier, the file permissions on a startup disk can be repaired with the help of Disk Utility. Note that beginning from OS X EI Capitan, disk permissions are automatically protected and there is no need to verify them with Disk Utility.
How do I repair my Mac startup disk?
Here are the steps for optimizing your Mac:
If you don’t want to repair disk permissions manually, you can easily perform the action with an utility we mentioned above — CleanMyMac X. It has the Maintenance module that will help you optimize your Mac, including verifying startup disk and repairing disk permissions. Changing color of bouncy ball dev c++. Thus, you’ll ensure that your Mac’s operating system is functioning properly. You can download CleanMyMac here.
Therefore, before defragging your Mac, try to perform the Mac disk cleanup to increase the disk speed. It’s an easy and risk-free process that will not take more than a few minutes.
General speedup tips
Sometimes your Mac needs a good kick-start to run smoothly. Here are some tricks to speed up your computer.
How do I improve my Mac performance?
1. Update macOS software
Try to update your software to the latest versions as it performs better than the previous ones. Usually system updates include performance and bug fixes that could be the reason of slowdowns.
2. Delete unnecessary files
Ensure that your Mac has at least 10 percent of total drive storage available at any time to perform background actions and provide enough space for temporary files, caches, and virtual memory. Once again, CleanMyMac X is a great solution for finding and removing useless and large files that take gigabytes of space on your Mac.
3. Stop programs from launching automatically
A large number of apps may launch simultaneously when you turn your Mac on. Some of them run in the background and are only visible in a menu bar, so it’s even hard to define if they’re actually running. You can stop them from loading by opening System Preferences, clicking on Users & Groups and then choosing Login Items. You’ll see a list of applications that launch during the startup. You can switch off the ones you don’t need by clicking the minus sign (-) button.
