You can use a OSX GUI Emacs in the form of Aquamacs which is configured to be more OSX like it its key commands and menus and integrates with the OS. One appeal of emacs is because emacs is mainly written in the language (e-lisp) that users can use to extend it there are a lot of scripts that add all sorts of functionality to the editor making it nearly as powerful as an ide. Emacs info nodes are accessible via search field in the Help menu on Mac OS X 10.6 and later. Menu item 'Open Selected File in Emacs' is shown in Services or context menu of other applications by default on Mac OS X 10.6 and later when absolute pathname-like text is selected. Reverse conversion in Kotoeri works even without selection.
Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some product or feature? Which versions are earlier (older) or later (newer, more recent) than the version currently installed? To find out, learn which version is installed now.
Mar 31, 2013 Installing Emacs. Ok, on to Emacs! First, of course, we need to actually install it. There are a few options available: Special Emacs builds like Aquamacs, which makes some modifications to make Emacs more OS X-like.; X11 Emacs running under XQuartz (you can install this version of Emacs using brew install emacs -with-x), which is traditional Emacs but runs under the X windowing system.
If your macOS isn't up to date, you may be able to update to a later version.
Which macOS version is installed?
From the Apple menu in the corner of your screen, choose About This Mac. You'll see the macOS name, such as macOS Mojave, followed by its version number. If some product or feature requires you to know the build number as well, click the version number to see it.
This example shows macOS Catalina version 10.15 build 19A583.
Which macOS version is the latest?
These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. And as updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.
If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.

700 Mhz and 800 Mhz eMacs maxed at Mac OS X 10.4.11 (link addresses how to upgrade).
No eMac is able to run off Mac OS 9 retail, and must use the prebundled copy of their eMac discs to install Mac OS 9 for use as bootable or Classic version of Mac OS 9. August 2002 and later models required the restore directions to install Mac OS 9 as either a bootable or Classic version.
1 Ghz and higher eMacs max at Mac OS X 10.5.8 (even with 10.5 there is no Boot Camp support on eMacs, and slower emulation was the only option to run Windows directly on an eMac). Only one eMac model M8950LL/A, was able to boot both into Mac OS 9, and use Mac OS X 10.5 via the Startup Disk System Preference in Mac OS X. The rest of the newer models must have a separate partition or external Firewire hard drive with 10.4.11 or earlier to maintain Classic compatibility, and could not boot Mac OS 9 directly. This limited their compatibility of Mac OS 9 drivers.

Booting Mac OS 9 on supported eMacs may only be possible after formatting with the Mac OS 9 drivers, which will require an erase of the hard drive.
That said, if you must run Mac OS X 10.6 or later, you'll need a newer Apple machine from 2006 or later with an Intel processor. This tip addresses how to migrate data from old eMacs or any Mac model that has a G3, G4, or G5 processor to an Intel processor:
