Mac OS is the computer operating system that was designed for the Apple Macintosh computer. It was industrial by Apple. Apple created iPhone and many other modern products like iPod, iPhone, and iPad.

The first version of the Mac OS, part of the “Classic” Mac OS series, was initially released in the mid-eighties. It did not have a command line and at a time it could run only one application. The first version of the ‘Macintosh Operating System’ was named “Mac OS” .The version is 7.6; the most recent version is called Mac OS X. OS X has a modular design projected to make it easier to add new features to the operating system in the future.



If you’re worried about the file size of images you should opt for Image Optim, a free image density tool that is so extremely simple it’s mostly perfect, while still being actually helpful. The app works to shrink images without reducing image quality, which is achieved by packing several compression tools, including the popular PNGCrush, PNGOUT, JPEGrescan, jpeg Tran, JPEGOPTIM, and gifsickle, and using those tools to find the best compression limits, in addition to stripping color profile information, EXIF, and other metadata out from the raw files. ImageOptim supports a variety of file formats, including PNG, GIF, JPG, and animated GIFs, here’s quick look at the connection:

The clearness is unreliable in that it doesn’t express just how helpful this app is, or just how valuable the optimization is. There are some tricks to get the most out of it.


  1. Start over with the developer website and take ImageOptim and uncompress the files, if you plan on using it often, then you can simply drag the ImageOptim app into your applications.


  1. Open ImageOptim and have the window somewhere noticeable from the Finder windows.


  1. Start compressing image files with drag & fall into the apps window to begin compression, or use you can use the “Open” option provided in the File menu to select files manually.


Every image began within the ImageOptim app will immediately decrease down lossless; this is done by stripping the exit data and other useless details that (should) have no shock on the image quality, while reducing file size. No other steps are needed, though if you’re looking beyond a single file compression you can use a few tricks to speed up the process of groups of pictures.




That varies, but on typical the image size savings are about 15-35%, making it a useful and must-have device for web designers, developers, bloggers, app developers, or anyone else that wants to cut image file size supplies. Some files can be very compressed though, and there are instances where poorly optimized original data can be squeezed down as much as 50-60%, depending on what is the actually reason for the file to be unnecessarily large. ImageOptim is particularly effective for uncompressed files, but you should have sensation with just about any image document you sink at it. The app will report you the savings details for each image, and this will show you the net compression, if you throw a group of files at it.


For comfortable compression right from the Finder, there is also a part system service available to download that lets you right-click on images and it will compress the image directly from the OS X Finder.



You can optimize images in bulk by using a large drag & drop. The best way to launch the ImageOptim app first and have the icon sitting in your port while it’s active, navigate to the folder containing images you want to compress, select them all, then use a drag and drop onto the icon to start the process. JPG and GIF files will compress extremely fast, but PNG files can take a bit more time to optimize, and in all cases the amount of time it takes to compress the image varies depending on the picture resolution and the total file size. For huge group compression, this is one of the easiest ways.


ImageOptim is a free app and for those wanting to compress images. If you are someone who is blogging on an MAC system, this is one must have blogging tool for making your images web-ready. Many users find the EXIF easy to use for its GPS coordinates, camera shooting details and camera settings. Using the optimization tricks through ImageOptim strips all EXIF data, making a file successfully clean away from the rare photo data itself, which can also be the aim for many users.
