MacKeeper is a cleanup utility for macOS.MacKeeper was developed by ZeoBIT, later acquired by Kromtech, and is currently owned by Clario Tech. . MacKeeper software is exclusively available for Mac computers, with version 5 (5.10) supporting macOS 10.11-10.12 and version 6 compatible with macOS 10.13 and later.
The simplest such pairwise independent hash function is defined by the random key, key = (a, b), and the MAC tag for a message m is computed as tag = (am + b) mod p, where p is prime. More generally, k -independent hashing functions provide a secure message authentication code as long as the key is used less than k times for k -ways independent ...
[24] It recommends cryptographic erase as a more general mechanism. According to the University of California, San Diego Center for Magnetic Recording Research's (now its Center for Memory and Recording Research) "Tutorial on Disk Drive Data Sanitization" (p. 8): "Secure erase does a single on-track erasure of the data on the disk drive. The U ...
The history of macOS, Apple's current Mac operating system formerly named Mac OS X until 2011 and then OS X until 2016, began with the company's project to replace its "classic" Mac OS. That system, up to and including its final release Mac OS 9 , was a direct descendant of the operating system Apple had used in its Mac computers since their ...
After the data is sanitized, key generation is used to ensure that this data is secure and cannot be tampered with. Approaches such as the Rider optimization Algorithm (ROA), also called Randomized ROA (RROA) use these key generation strategies to find the optimal key so that data can be transferred without leaking sensitive information.
Mac Pro (Late 2013 or later) Mac Studio (2022) By using patch tools, macOS Monterey can be unofficially installed on earlier computers that are officially unsupported, such as the 2014 iMac and the 2013 MacBook Pro. [30] Using these methods, it is possible to install macOS Monterey on computers as old as a 2008 MacBook Pro and iMac and 2009 Mac ...

Using MAC = H(key ∥ message ∥ key) is better, but various security papers have suggested vulnerabilities with this approach, even when two different keys are used. [ 1 ] [ 7 ] [ 8 ] No known extension attacks have been found against the current HMAC specification which is defined as H ( key ∥ H ( key ∥ message )) because the outer ...
