Mac OS El Capitan was released to manufacturing on 20th September 2015, almost three and a half years ago. Its latest version 10.11.6 (15G22010) was released on 9th July 2018, almost 7 months ago. It runs on the platform including x86-64. Mac OS El Capitan is preceded by OS X 10.10 Yosemite and it is succeeded by macOS 10.12 Sierra.
System requirements
All Macintosh PCs that can run Mountain Lion, Mavericks, or Yosemite can run El Capitan in spite of the fact that not the majority of its highlights will take a shot at more seasoned PCs. For instance, Apple noticed that the recently accessible Metal API is accessible on “all Macs since 2012”.
The following computers can run mac OS el Capitan provided that they must have a ram of 2GB or more –
- MacBook: Late 2008 or newer
- MacBook Air: Late 2008 or newer
- MacBook Pro: Mid 2007 or newer
- Mac Mini: Early 2009 or newer
- iMac: Mid 2007 or newer
- Mac Pro: Early 2008 or newer
- Xserve: Early 2009
Of these PCs, the accompanying models were outfitted with 1GB RAM as the standard alternative on the base model when they were sent initially. They can possibly run OS X El Capitan in the event that they have at any rate 2GB of RAM-
- iMac: Mid 2007
- iMac: Early 2008
- Mac Mini: Early 2009
The accompanying PCs bolster highlights, for example, Handoff, Instant Hotspot, AirDrop between Mac PCs and iOS gadgets, just as the new Metal API:
- iMac: Late 2012 or newer
- MacBook: Early 2015 or newer
- MacBook Air: Mid 2012 or newer
- MacBook Pro: Mid 2012 or newer
- Mac Mini: Late 2012 or newer
- Mac Pro: Late 2013
The redesign differs in size contingent on which Apple Mac PC it is being introduced on, in many situations, it will require around 6 GB of plate space.
What is DMG File
DMG represents Disk picture document. It is much the same as the ISO record which keeps running on Windows yet it keeps running on Mac OS. DMG is area by a segment of optical stockpiling media. DMG record is utilized rather than an optical plate. It has .dmg augmentation. Past Disk Image File has .smi and .img augmentation which depends on New Disk Image Format (NDF). The present DMG document depends on Universal Disk Image Format (UDIF). Widespread Disk Image Format underpins Zlib, ADC, bzip2 pressure calculation. DMG record depends on figuring out however it’s documentation isn’t discharged by Apple Company. It is more secure than ISO record. Plate Image Files are distributed with a MIME kind of utilization which is known as x – apple circle picture. There are distinctive record frameworks inside circle picture.
What is ISO file
ISO document is the copy or file record that contains every one of the information of optical plate-like CD or DVD. It represents the International Standard Organization. It is utilized to duplicate the precise record in light of the fact that in typical duplicate, it needs header document yet in an ISO record, every one of the information including the header record is The ISO name is taken from ISO9660 on the grounds that this component is utilized in circles yet ISO record has UDF(ISO/IEC 13346) document framework is utilized which is generally utilized in DVDs and Blu-beam Disks. It accompanies .iso augmentation.
