2 Training and Education in Bangla: SaLearningSchool.com Training and Education in English: Ask questions and get answers Offline IT Training:

3 Learning MAC OS by Comparing with Windows Basic understanding of Mac Basic operations in Mac Getting around Launch applications Disk management and maintenance defragmentation User accounts and security Local user accounts and security

4 File and application management Install and uninstall applications Printing and peripherals Core Networking Setup core networking features Troubleshooting – built-in

5 Network Services and Sharing Providing to the network Sharing with the network Consume network services System preferences Configure the system Backup and recovery Built in backup and recovery Terminal Windows Full Unix Shell

6 Built in Apps Using Windows based Resources Ongoing maintenance Remote control Using remote desktop Advanced integration with Windows Mac into active directory Built in and commercial tools

7 Missing links Getting key windows features Bootcamp Windows on a Mac

8 Disk drives on your MAC View disk contents Format disks Defragment disks Mac automatically does this but not 100% perfect Disk images & ISOs Work with image files Raid (work with and create) Check disks [similar to windows check disk/scan disk]

9 Managing and working with image files Such as ISO image files

10 Most disk related operations can be performed using the built in Disk Utility tool Disk utility: how to open Finder->applications->utilities->disk utility Alternative: When Finder window is active -> then click Go menu -> Utilities-> disk utility Shortcut: Shift + command + U Or ctrl + space, then type disk utility Disk Utility Can show all hard drives and volumes Volumes inside hard drives Can erase, partition, restore, raid functionality (multiple drives) Run Check disk [mark bad blocks/sectors in the drive] Restore image to this drive and volume Options: First Aid, Erase, Partition, RAID, Restore First aid: check disk equivalent

11 Mac Automatically defrags Not always, not by 100% No built-in apple tool to defrag [that you can execute] iDefrag – commercial defragment tool When you have multiple drives, you can create RAID Can be useful for servers Mirrored, striped, concatenate Set block size, repair RAID

12 Disk utility [open] Create new disk image File->new->disk image Set the parameters for the disk image such as Volume name, format, encryption, partitions, image format Double click will mount it Will be listed in list devices Need to eject You can right clean and clean up the image After copy from/to, you need to eject Right click and eject [un-mount as a drive but still as a drive, double click will mount]

13 Kind of zip file Distributed applications as image [.dmg] Right click and compress [installer] 10 MB, will take 10mb, zip will reduce the size Remount Double click Then Transfer file, move around in the internet Treat it as disk You can Erase image using the disk utility Good way to archive files We can move to trash and clean

14 Mac has built in ability to burn images into cds/DVDs Disk utility->file->new->blank disk image 660 MB cd, partition cd/dvd, dmg files take all the space as mentioned Format and mount Images menu Right click on dmg file Checksum match can help Image [from disk utility] Convert to cd/dvd, extension.cdr [CD/DVD master]

15 Not iso but cdr Can verify You can convert to.iso Un-mount the.iso.iso double click will still mount it Copy your files into the image Right click-> burn

16 User Accounts Anti-malware Filevault Firewall Misc Security Safari Security

17 System Preferences -> Users Accounts Mac is not much safer than windows [fundamentally] Though will get affected less as there are less viruses and hackers targeting Mac platform Will get more and more virus and malware over time Virus creators want to get more exposure; so windows has more of them If you do not have protection, you will get some in your mac All big Anti-virus companies have Mac versions

18 When you signup for Apple Extra Services Will provide you an antivirus software as well dotMac Service: Antivirus Program System Preferences System -> Accounts [know about mobile me service by Apple] Configure Login Accounts Login items Set applications to run automatically Mobile me service affects some features Click the lock to make changes in the accounts Enable and use this Then you can add new account Set account type Administrator, Group, sharing Tabs in the window: Password and Login Items Add to login items Click the + button

20 System preferences- > Personal -> security Tabs in the window: General, FileVault, Firewall General Disable auto login Password requirement Log out after X minutes Use secure virtual memory Disable remote control infrared receiver Pair to remote Disable infrared remote control Set account type Administrator, Group, sharing

21 FileVault Encrypt files in your home folder Set master password Turn on FileVault Filevault is for local, not for remote Encrypt using login password For extra security: Master password Turn filevault on Per account basis Will take a while Most Mac has infrared receiver Options for the infrared [remote]configuration

22 Default firewall Default allow incoming for basic services Allow all incoming connections Allow only essential services Set access for specific services and applications Logging option to figure out what are failing Stealth mode Deny connection but do not tell anyone More secure but not much logging

23 Safari menu ->Block pop-up windows Emptying the cache, good security work Private browsing No history No id/password saving option Safari -> preferences Auto fill can be a security option Give access to address book card User names and passwords Other forms What to auto fill Disabling can be more secure

24 Develop Menu Security sensitive activity Change the user agent Make the browser behave something differently

25 Warn when visiting fraudulent site Enable plug ins Enable java Block pop-up windows Cookies Local Database Configure space Show databases Persist database test, persist storage Per database default
