macOS Install Karne Se Pehle Kya Chahiye?

  • macOS ke saath compatible Apple Mac
  • Stable internet connection
  • MacBook ke liye connected charger
  • Kam az kam 16GB USB; 32GB USB recommended hai
  • Administrator account aur password
  • Important files ka Time Machine ya external-drive backup
  • Compatible macOS ka full installer

Step 1: Apne Mac ka Model aur Processor Check Karein

Apple menu se About This Mac open karein. Yahan model, year aur processor/chip nazar aayega. Agar “Chip: Apple M1, M2, M3…” jaisa text ho to aapka Mac Apple silicon hai. Agar “Processor: Intel…” ho to woh Intel Mac hai.

Har Mac har macOS version support nahi karta. Installer download karne se pehle Apple ki official compatibility information check karein. Incompatible version install karne par installer ruk sakta hai ya prohibition symbol dikh sakta hai.

Step 2: Backup Banayein

Upgrade install aam tor par personal data ko rakhta hai, lekin clean installation mein disk erase hoti hai. Is liye:

  1. External drive connect karein.
  2. System Settings mein General > Time Machine open karein.
  3. Backup disk select karke complete backup run karein.
  4. Critical documents ko separately cloud ya doosri drive par bhi copy kar lein.

Backup ko verify kiye baghair internal disk erase na karein.

Step 3: Full macOS Installer Download Karein

Full installer Apple ke App Store, Software Update, browser ya Terminal se download kiya ja sakta hai. Download complete hone ke baad installer Applications folder mein “Install macOS [version]” naam se hona chahiye. Agar installer khud open ho jaye to usay quit kar dein—abhi installation start nahi karni.

Apple ki official download aur bootable-installer instructions yahan milengi: Create a bootable installer for macOS.

Step 4: USB Ko Tayyar Karein

USB ko Mac mein directly connect karein. Is process mein USB ka sara data erase hoga, is liye zaroori files pehle copy kar lein.

  1. Disk Utility open karein.
  2. View > Show All Devices select karein.
  3. Sidebar mein USB ka top-level device select karein.
  4. Erase click karein.
  5. Name: MyVolume
  6. Format: Mac OS Extended (Journaled)
  7. Scheme available ho to: GUID Partition Map
  8. Erase complete hone ke baad Disk Utility close karein.

Step 5: Terminal Se Bootable USB Banayein

Applications > Utilities > Terminal open karein. Apne downloaded installer ke mutabiq Apple ka official createinstallmedia command use karein. USB ka naam MyVolume rakha ho to common examples yeh hain:

macOS 27 Golden Gate

sudo /Applications/Install\ macOS\ 27\ Golden\ Gate.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

macOS Tahoe 26

sudo /Applications/Install\ macOS\ Tahoe.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

macOS Sequoia 15

sudo /Applications/Install\ macOS\ Sequoia.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
  1. Command paste karke Return press karein.
  2. Admin password type karein. Terminal password ke characters show nahi karega—yeh normal hai.
  3. USB erase confirm karne ke liye Y type karke Return press karein.
  4. Agar Terminal removable volume access maange to OK karein.
  5. “Install media now available” jaisa message aane tak USB remove na karein.

Agar “command not found” aaye to installer ka exact naam aur Applications folder location check karein. Agar installer invalid bataya jaye to installer dobara official Apple source se download karein.

Step 6: USB Se Boot Kaise Karein?

Mac ko internet se connected rakhein, kyun ke installer ko model-specific firmware aur doosri information ki zaroorat ho sakti hai.

Apple silicon aur Intel Mac ke USB boot methods

Apple Silicon Mac (M-series)

  1. Mac ko completely shut down karein.
  2. Bootable USB directly connect karein.
  3. Power button press karke hold rakhein.
  4. “Loading startup options” aur boot volumes nazar aane par button chhor dein.
  5. USB installer select karke Continue click karein.

Intel Mac

  1. Mac shut down karein aur USB connect karein.
  2. Mac on karte hi Option (⌥) / Alt key hold karein.
  3. Startup Manager aane par key chhor dein.
  4. USB installer select karke Return press karein.

Agar Intel Mac mein Apple T2 Security Chip ho aur USB boot na ho, Recovery ke Startup Security Utility mein external/removable media se boot allow karna par sakta hai.

Step 7: Upgrade Install Ya Clean Install?

Option A — Existing Data Rakh Kar Reinstall/Upgrade

macOS Utilities mein Install macOS select karein aur current macOS volume choose karein. Disk Utility se internal drive erase na karein. Phir bhi backup recommended hai.

Option B — Clean Installation

Clean install purana data, accounts, apps aur settings remove karta hai.

  1. Installer/Recovery screen se Disk Utility open karein.
  2. View > Show All Devices select karein.
  3. Internal section mein existing macOS volume—aksar Macintosh HD—select karein.
  4. Erase ya available ho to Erase Volume Group click karein.
  5. Name: Macintosh HD
  6. Format: APFS
  7. Erase complete hone ke baad Disk Utility quit karein.
  8. Install macOS select karke Macintosh HD par installation start karein.

Warning: Sirf tab erase karein jab backup verified ho aur aap clean install hi chahte hon. Trade-in ya sale ke liye supported Apple silicon/T2 Macs par Erase Assistant zyada munasib ho sakta hai.

Step 8: Installation Complete Karein

Installation ke duran Mac kai dafa restart ho sakta hai. Charger connected rakhein, lid close na karein aur power interrupt na karein. Agar restart ke baad Mac dobara USB installer open kare, internal Macintosh HD ko startup disk select karein ya USB safely disconnect karke restart karein.

Setup Assistant mein country/region, Wi-Fi, Apple Account, privacy, user account aur FileVault options complete karein. Time Machine backup ho to Migration Assistant se data restore kiya ja sakta hai.

Installation Ke Baad Zaroori Kaam

  • System Settings > General > Software Update se latest updates install karein.
  • Wi-Fi, Bluetooth, audio, camera, keyboard aur ports test karein.
  • Time Machine backup dobara configure karein.
  • Required apps ko official sources se reinstall karein.
  • Important files restore karke verify karein.

Common Problems aur Solutions

USB Startup Options Mein Show Nahi Ho Rahi

  • USB ko hub ke bajaye directly connect karein.
  • Doosra USB port ya compatible adapter try karein.
  • Installer dobara create karein.
  • Intel T2 Mac par external boot permission check karein.

Prohibition/Circle Symbol Aa Raha Hai

Aksar iska matlab macOS version Mac ke saath compatible nahi. Apne exact Mac model ke liye supported installer use karein.

“Installer Is Damaged” Ya Verification Error

  • Date/time aur internet connection check karein.
  • Purana installer delete karke Apple se fresh copy download karein.
  • USB dobara erase karke createinstallmedia repeat karein.

Internal Disk Disk Utility Mein Nahi Dikh Rahi

View > Show All Devices select karein. Non-essential accessories disconnect karke restart karein. Agar physical internal drive phir bhi show na ho ya erase fail ho to hardware service ki zaroorat ho sakti hai.
