OnyX is a multifunction utility that you can use to verify the structure of the system files; run miscellaneous maintenance and cleaning tasks; configure parameters in the Finder, Dock, Safari, and some Apple applications; delete caches; remove certain problematic folders and files; rebuild various databases and indexes; and more.OnyX is a reliable application which provides a clean interface to many tasks that would otherwise require complex commands to be typed using a command-line interface.IMPORTANT:There is a specific version of OnyX for each major version of the operating system.Use the correct version, and don't try to use a version intended for an earlier operating system.
Mac Os Disk Utility Download
You may wish to partition a disk to divide it into separate containers or because you want to install multiple operating systems. How you do this will depend on the version of macOS you are running. On newer Macs rather than create a partition you should create a volume.
A bootable macOS (previously, OS X) install disk is a portable device containing all the necessary installation files for a selected version of macOS. Why would you want to create an external boot drive for your Mac?
GrandPerspective is a small utility application for macOS that graphically shows the disk usage within a file system.It can help you to manage your disk, as you can easily spot which files and folders take up the most space.It uses a so called tree map for visualisation. Each file is shown as a rectangle with an area proportional to the file's size.Files in the same folder appear together, but their placement is otherwise arbitrary.
14 Jan 2023 GrandPerspective 3.0.1 has been released and is available for download from Sourceforge.It fixes just one bug. It was not possible to load scan data files larger than 4 GB.Now it is, but it is still not recommended though as it is slow.
10 Jul 2022 GrandPerspective 3.0.0 has been released and is available for download from Sourceforge and the App Store.Most notably, it includes the ability to quickly refresh a view.This functionality is very similar to re-scan but is much faster;refresh only re-scans the contents of folder that have changed since the previous scan.Implementing this functionality triggered significant changes to the implementation, which is the reason for bumping the major version.
17 Apr 2022 GrandPerspective 2.6.3 has been released and is available for download from Sourceforge.It includes various fixes and one minor feature improvement: the progress panel shows folders where significant time is spent.
3 Feb 2022 GrandPerspective 2.6.2 has been released and is available for download from Sourceforge and the App Store.It fixes the known issue (unwanted black pixels during zoom-in animation) introduced in Version 2.6.1.
29 Jan 2022 GrandPerspective 2.6.1 has been released and is available for download from Sourceforge.It now animates changes to the tree map view.In particular, when you zoom in or out and when you change to the focus, the change is animated.
16 Jan 2022 GrandPerspective 2.6.0 has been released and is available for download from Sourceforge.It provides keyboard navigation. Very useful. Why did this take so long?Also minor improvements to the progress panel and selected item visibility.
21 Nov 2020 GrandPerspective 2.5.4 has been released and is available for download from Sourceforge.It features only one change but a notable one.After fifteen years, there's a new icon; it complies with the new Big Sur guidelines.I hope you like it.For those that liked the old icon, fear not, it's still used as a logo at various places.
15 Nov 2020 GrandPerspective 2.5.3 has been released and is available for download from Sourceforge.It is released as a Universal App so that it can also run on Apple Silicon.It also improves support for macOS Big Sur. Most notably, the toolbar has a new look and feel.
20 Sep 2020 Two significant milestones have passed.First, GrandPerspective's first release was exactly fifteen years ago.Second, it has been downloaded more than two million times.Hip, hip, hurray!
5 Jul 2020 GrandPerspective 2.5.2-L1 has been released and is available for download from Sourceforge and the App Store.The only change with respect to Version 2.5.2 is that the translations in Chinese, German, Italian, and Turkish are fully complete again.In other words, the text for the features newly added in Version 2.5.2 is now also translated.
28 Jun 2020 GrandPerspective 2.5.2 has been released and is available for download from Sourceforge.It improves the selection logic for filters with multiple tests.It also includes updated Chinese, German, Italian, and Turkish translations.
21 Jun 2020 GrandPerspective 2.5.1 has been released and is available for download from Sourceforge.It lets you quickly search files by name.It also includes drawing (performance) improvements and fixes some crashes.
21 Jan 2020 GrandPerspective 2.4.1 has been released and can be downloaded from Sourceforge.It supports dropping folders onto the Start window.It also includes two bug fixes and updated Turkish translations.
10 Jan 2020 GrandPerspective 2.4.0 has been released and can be downloaded from Sourceforge.It features a new Control panel, which replaces the old drawer which has been deprecated by Apple and did not fully support Dark Mode.The new panel reduces screen clutter as it is shared by all views and can be placed where you want.This new version also includes a fix for an issue that could cause crashes when scanning data volumes.

Extensive help documentation
GrandPerspective has been released as Open Source under the GNU General Public License.The official release files are available from the GrandPerspective download area at SourceForge.The latest release (Version 3.0.1) consists of two files:GrandPerspective-3_0_1.dmgThis is the main release file.It contains all you need to run the application.To install it, open the disk image and drag the application icon onto your Applicationsfolder, or wherever you want to put it onto your file system.Next run the application by clicking on the icon.
GrandPerspective is also distributed via the App Store as requested by several users.This exposes the app to a wider audience, including some who will only install software distributed via the App Store.I charge a small fee of $2.99 for the app when it is downloaded from there to cover the required developer program membership and other development costs.
GrandPerspective is certainly not the first of its kind. Tree maps have been around for a while, and their application to file systems is not novel either. A few other disk usage visualisation tools that employ tree maps are:Sequoiaview, which is the one I bumped into first, because as it happens it was developed in Eindhoven, which is where I currently live.
KDirStat and WinDirStat I need to mention, if only because they are also hosted on SourceForge. I haven't tried them though.
Disk Inventory X is noteworthy because it also runs on macOS.
So, why GrandPerspective?Well, as you may have guessed it's a fun little coding project and I needed to pick something to code on my new Mac Mini.Having said that, it does have a few things going for it.Firstly, GrandPerspective is developed specifically for macOS, which narrows the immediate competition down to Disk Inventory X, as far as I'm aware.Secondly, GrandPerspective has its own way of visualising directory trees.The layout algorithm that is used is simple and effective, but novel to the best of my knowledge.Also, the file rectangles are drawn to be as clear and unobtrusive as possible. Whether you like it or not is a matter of taste, but you've got a choice.Thirdly, GrandPerspective will intentionally be kept as basic as possible.It should do one thing only, and do it well. That means it is a lean and mean application.GrandPerspective's memory requirements and the size it occupies on disk are pretty minimal.For those concerned about disk space, the latter must count for something, right?Finally, it has a cute logo that will enhance anyone's Dock. ;-) 2ff7e9595c
