<p>First of all, I'm a complete novice, so I apologize for my ignorance. I have a MacBook where I installed Bitcoin Core v0.15.1 (64-bit).  In my wallet, it shows no BTC. (Note: I cannot find a file on my laptop called &quot;wallet.dat&quot;). Myy hard drive isn't big enough to download the entire blockchain.  Would this version of Bitcoin Core show a BTC balance even if the entire blockchain hasn't been sync'd, or will it only show an accurate BTC balance in my wallet only if the blockchain is sync'd with my laptop?  Again, I'm a novice, so I apologize for using incorrect terminology.  Thank you.</p>

First of all, I'm a complete novice, so I apologize for my ignorance. I have a MacBook where I installed Bitcoin Core v0.15.1 (64-bit). In my wallet, it shows no BTC. (Note: I cannot find a file on my laptop called "wallet.dat"). Myy hard drive isn't big enough to download the entire blockchain. Would this version of Bitcoin Core show a BTC balance even if the entire blockchain hasn't been sync'd, or will it only show an accurate BTC balance in my wallet only if the blockchain is sync'd with my laptop?
